refactor(feed): port refresh batch to Effect for concurrency and timeout

Replace the hand-rolled worker pool (mapWithConcurrency) with an Effect
program (src/effects/feed-refresh.ts): Effect.forEach bounds in-flight
fetches, Effect.timeout bounds each feed via the Clock service, and
failures fold to null so a bad feed never fails the batch. Per-feed
apply-as-it-lands is preserved — the apply callback runs inside each
feed's own fiber, so there is no Promise.all barrier.

Store boundary unchanged: refreshAllFeeds runs the program through
Effect.runPromise, keeping runAutoDownload + flushPendingSave after the
batch and isLoadingFeeds around it.

Adds TestClock-driven tests (tests/feed-refresh-effect.test.ts) that pin
concurrency, per-feed apply, timeout, and failure isolation without real
20s waits. Pins effect@^3 (V4 is in beta).

+  - New exported pure function `episodeInWindow(ep: Episode, now: Date): boolean` — returns `true` when `ep.pubDate` is missing/not a valid `Date` (fail-safe: never drop an undatable episode) OR `ep.pubDate.getTime() >= now.getTime() - EPISODE_WINDOW_DAYS * 24 * 3600 * 1000`.
+  - New exported pure function `episodeIsPersistable(ep: Episode, downloadedIds: Set<string>, now: Date): boolean` — returns `true` when `downloadedIds.has(ep.id)` OR `episodeInWindow(ep, now)`.
   - New (module-private) async helper `readDownloadedEpisodeIds(): Promise<Set<string>>` — reads `getConfigFilePath("downloads.json")` with `Bun.file`, returns the `episodeId`s of records whose `status` equals `DownloadStatus.COMPLETED`; returns an empty set on any error or missing file. Note: an episode whose download is merely in-flight is NOT exempted; it will be re-included by the next save after completion, since the in-memory `feed.episodes` still holds it — document this in the function comment.
   - `saveFeedsToFile(feeds: Feed[])` — before calling `updateConfig`, map each feed to `{ ...feed, episodes: feed.episodes.filter(ep => episodeIsPersistable(ep, downloadedIds, new Date())) }`. The downloaded-ids lookup is async, so wrap the whole body in a fire-and-forget async IIFE (`.catch(() => {})`) that preserves the existing sync/fire-and-forget signature; on any lookup failure, save the feeds unpruned (never lose data on an error path).
   - `loadFeedsFromFile()` — after `reviveDates`, apply the same prune to the loaded feeds; if the prune removed at least one episode, call `saveFeedsToFile(pruned)` to rewrite `config.json` (this is the startup cleanup for legacy configs). `await` the prune path deterministically (the function is already async).

   - `fetchEpisodes(feedUrl, limit, feedId?)` parses the whole feed, stores ALL episodes in the module-level `fullEpisodeCache` Map, returns the first `limit`.
   - `refreshFeed` / `refreshAllFeeds` pass the fetched window through `applyRefreshedEpisodes`, which REPLACES `feed.episodes` when ids differ (`sameEpisodes` id-set compare; unchanged → keep object identity and skip save — this order-stability contract is pinned by `tests/feed-refresh.test.ts` and must keep passing).
   - `loadMoreEpisodesForFeed` grows the displayed window from `fullEpisodeCache` (fetching+parsing the full feed when the cache is cold — e.g. after a restart), tracking progress in `episodeLoadCount`.

 - Style: `feed.ts` is tab-indented WITH semicolons. New utils file: match `src/api/rss-parser.ts` style (2-space, no semicolons).
 
 deliverables:
 
-- New `src/utils/episode-merge.ts` (pure, store-free, unit-testable):
-  - `mergeEpisodes(existing: Episode[], fetched: Episode[], cap: number): Episode[]` — union by `ep.id`; on id collision the `fetched` copy wins (fresh metadata); result sorted by `pubDate` descending; truncated to `cap` entries (the OLDEST are dropped — after sorting, a plain `.slice(0, cap)`).
+- `src/utils/feeds-persistence.ts` (the canonical window owner):
+  - Rename the retention constant to `EPISODE_WINDOW_DAYS = 30` — it now bounds the volatile cache/list as well as persistence.
+  - New exported `episodeInWindow(ep: Episode, now: Date): boolean` — `pubDate >= now - EPISODE_WINDOW_DAYS`; missing/invalid pubDates are ALWAYS kept (fail-safe mirror of the persistence rule, so cache and disk can never disagree about an undatable episode). `episodeIsPersistable` becomes `downloadedIds.has(ep.id) || episodeInWindow(ep, now)`.
+- Rework `src/utils/episode-merge.ts` (pure, store-free, unit-testable):
+  - `mergeEpisodesInWindow(existing: Episode[], fetched: Episode[], now: Date): Episode[]` — union by `ep.id`; on id collision the `fetched` copy wins (fresh metadata); result sorted by `pubDate` descending; pruned to the lifecycle window via `episodeInWindow` (out-of-window episodes dropped, undated kept). No count cap — the bound is the date.
   - Invariants: never mutates inputs; stable output for `existing=[]`; entries with invalid `pubDate` sort as newest (use `getTime()`, treat `NaN` as `+Infinity` with a small `ts()` helper).
 - `src/stores/feed.ts`:
-  - New constant `MAX_EPISODES_IN_MEMORY = 500` (comment: per-feed bound on both the cached parse results and the merged in-memory window; 500 covers years of a weekly show's history while capping a 20-subscription install at 10k episodes).
-  - `fetchEpisodes`: cap what goes into `fullEpisodeCache` — `fullEpisodeCache.set(feedId, allEpisodes.slice(0, MAX_EPISODES_IN_MEMORY))` (the array is already sorted newest-first via `sortEpisodesReverseChronological`). The LIMIT window returned to callers is unchanged.
+  - Delete `MAX_EPISODES_IN_MEMORY` — no episode-count bound anywhere.
+  - `fetchEpisodes`: window-filter the parsed feed (`allEpisodes.filter(ep => episodeInWindow(ep, new Date()))`) BEFORE caching and returning: `fullEpisodeCache.set(feedId, windowed)` and `episodes: windowed.slice(0, limit)`. The limit is a page size; the window is the bound.
   - `applyRefreshedEpisodes(prev, feedId, episodes)`: replace the `sameEpisodes` replace-with-fetched logic with merge semantics:
-    - Compute `merged = mergeEpisodes(f.episodes, episodes, MAX_EPISODES_IN_MEMORY)`.
+    - Compute `merged = mergeEpisodesInWindow(f.episodes, episodes, new Date())`.
     - Unchanged detection must compare the FETCHED window against the corresponding prefix of the existing list, i.e. keep a small `sameRefreshWindow(existing: Episode[], fetched: Episode[])` helper next to (and replacing the use of) `sameEpisodes`: `fetched.length === 0 → true`; otherwise compare id-sets of `fetched` and `existing.slice(0, fetched.length)`. Rationale: with union semantics `merged` legitimately contains episodes beyond the fetched window, so comparing full lists would bump `lastUpdated` on every refresh and resurrect the order-flapping bug `tests/feed-refresh.test.ts` guards.
     - Return unmodified `prev` when every feed's window is unchanged (preserve the existing identity-no-save contract); on change, set `{ ...f, episodes: merged, lastUpdated: new Date() }`.
     - Delete the now-unused `sameEpisodes` if nothing else references it (grep first: `grep sameEpisodes src tests`).
-  - `loadMoreEpisodesForFeed`: cap the cold-refetch cache the same way after `parseEpisodesIncremental` (it's unsorted there — wrap with `sortEpisodesReverseChronological` before capping); everything else (window growth by `MAX_EPISODES_REFRESH`, `hasMoreEpisodes` comparing `episodeLoadCount < cached.length`) works unchanged against the capped cache.
-- `tests/feed-volatile-merge.test.ts` (new) — see tests section.
+  - `loadMoreEpisodesForFeed`: window-filter the cold-refetch cache the same way after `parseEpisodesIncremental` (it's unsorted there — wrap with `sortEpisodesReverseChronological` before filtering). Fetch-more stepping is mode-dependent: DATE mode advances the loaded window by a `FETCH_MORE_WINDOW_DAYS` (14) band past the oldest loaded episode — a daily show gains ~2 weeks of episodes per press, not a fixed count — with a +1 minimum so a sparse band can't wedge the button into a no-op; COUNT mode keeps the fixed `MAX_EPISODES_REFRESH` (50) chunk. `hasMoreEpisodes` still compares `episodeLoadCount < cached.length`.
+- `tests/feed-volatile-merge.test.ts` (reworked) — see tests section.
 
 steps:
 
 1. Read `src/stores/feed.ts` fully and `tests/feed-refresh.test.ts` + `tests/feed-pagination.test.ts` (they pin the contracts you must not break; reuse their harness).
-2. Write `src/utils/episode-merge.ts` with `mergeEpisodes`.
-3. Integrate in `feed.ts`: replace `sameEpisodes` usage with `sameRefreshWindow` + `mergeEpisodes` in `applyRefreshedEpisodes`; cap `fullEpisodeCache` writes in `fetchEpisodes` and `loadMoreEpisodesForFeed`; add `MAX_EPISODES_IN_MEMORY`.
+2. Rework `src/utils/episode-merge.ts` to `mergeEpisodesInWindow`; add `episodeInWindow` (and rename `PERSISTED_WINDOW_DAYS` → `EPISODE_WINDOW_DAYS`) in `feeds-persistence.ts`.
+3. Integrate in `feed.ts`: replace `sameEpisodes` usage with `sameRefreshWindow` + `mergeEpisodesInWindow` in `applyRefreshedEpisodes`; window-filter `fullEpisodeCache` writes and the returned window in `fetchEpisodes` and `loadMoreEpisodesForFeed`; delete `MAX_EPISODES_IN_MEMORY`.
 4. Run the existing feed tests — all must pass unchanged (merge must keep order stability and pagination intact).
 5. Write the new tests, run, then full suite + lint.
 
 tests:
 
 - New `tests/feed-volatile-merge.test.ts`:
-  - Pure unit (Arrange–Act–Assert) for `mergeEpisodes`:
+  - Pure unit (Arrange–Act–Assert) for `mergeEpisodesInWindow(existing, fetched, now)`:
     - dedupe on collision, fetched copy wins (mutate title in the fetched twin, assert the merged entry shows the new title).
     - union of disjoint lists sorted by `pubDate` desc.
-    - cap trimming drops the oldest: `cap=2`, three episodes spanning three days → the two newest survive.
+    - window prune drops out-of-window episodes from BOTH inputs and keeps undated (NaN pubDate) episodes.
     - input arrays not mutated.
   - Store integration (harness per `tests/feed-refresh.test.ts`: temp `XDG_CONFIG_HOME` BEFORE imports, `Bun.serve` on port 0 serving generated RSS, fake timers):
     - Refresh-keeps-volatile-window: serve 3 episodes at t0, `addFeed`; then serve the same 3 plus 2 new ones, `refreshFeed`. Assert `feed.episodes.length === 5` AND `lastUpdated` advanced AND a second identical refresh leaves `lastUpdated` untouched (window-compare, not union-compare).
-    - Bounded cache: serve 600 items (generate programmatically), refresh, then `hasMoreEpisodes` grows only to the cap: loop `loadMoreEpisodes` until it returns false and assert total loaded ≤ `MAX_EPISODES_IN_MEMORY` (import the constant from the store module if exported, else assert `=== 500`).
+    - Boundary: a 25-day-old episode loads; a 70-day-old episode is neither visible nor cached initially, but fetch-more surfaces it (volatile).
+    - Date stepping: 30 episodes at 3-day spacing — each fetch-more press reveals the next 2-week band (24 → 28 → 30), NOT a fixed 50-chunk.
+    - Count-mode global step: two feeds with staggered dates — one Feed-page press adds the configured N most-recent UNLOADED episodes across ALL shows (N total, not N per show), via the k-way frontier merge in `loadMoreAllFeedsByCount`.
+    - Out-of-window never cached: 600 items at 2h spacing span ~50 days — only the in-window tail is loadable (fewer than the old 500 cap), `hasMoreEpisodes` flips false there.
+    - No count ceiling: 600 items at 1h spacing (all within 25 days) are ALL loadable — the bound is the date, not a number.
+  - Clock constraint: these tests run under fake timers, and a large `vi.advanceTimersByTime` (past ~5 days of fake time) makes Bun 1.3.8 hang every subsequent network fetch — the boundary is pinned with relative pubDates, never by moving the clock across it.
 - Existing suites that must keep passing: `tests/feed-refresh.test.ts`, `tests/feed-pagination.test.ts`, `tests/feed-refresh-spinner.test.tsx`.

-- After a simulated restart (fresh store boot from a pruned config), fetch-more re-parses the feed and can surface over-30-day episodes in volatile memory.
+- Per-feed cached/parsed episodes are exactly the in-window set: nothing outside the last `EPISODE_WINDOW_DAYS` days is cached or loadable, and everything inside is (no count ceiling).
+- After a simulated restart (fresh store boot from a pruned config), fetch-more re-parses the feed and applies the same window to the cache.

- * Two behaviors from the bounded-feed-lifecycle work:

- *      (the fetched copy wins on id collision), so a refresh never shrinks
- *      the session's visible window; the union is capped per feed at
- *      MAX_EPISODES_IN_MEMORY.
- *   2. The per-feed parse cache is capped at MAX_EPISODES_IN_MEMORY, so
- *      loadMoreEpisodes can never surface more than the cap and
- *      hasMoreEpisodes flips false there.
+ * The episode list cache (what the Feed and My Shows pages show) is bounded by
+ * the user's preference: a date window (default 60 days) or a count (default
+ * 25). The full parse cache holds ALL episodes; fetch-more pages beyond the
+ * bound from that cache (volatile — never written back). These tests pin:
+ *   1. mergeEpisodesBounded unions refreshed episodes with what's in memory
+ *      (fetched copy wins on id collision) and prunes by the supplied keep
+ *      predicate (count or date). Undated episodes are always kept.
+ *   2. The store bounds the visible list by the configured mode, but the
+ *      full parse cache survives — fetch-more pages beyond the bound.
+ *   3. Refresh merge never shrinks the in-memory list except via the bound.
  *
- * Unchanged-refresh detection compares the fetched window against the
- * corresponding PREFIX of the merged list (sameRefreshWindow) — comparing
- * full lists would bump lastUpdated on every refresh because the merged list
- * legitimately holds episodes beyond the fetched window.
+ * Clock constraint: these tests run under vi.useFakeTimers, and a LARGE
+ * vi.advanceTimersByTime (past ~5 days of fake time) makes every subsequent
+ * network fetch hang in Bun 1.3.8's fake-timer implementation. The date
