Michael Freno 26729fa5e6 feat(feed): make episode cache bound user-configurable (date window or count)

Add episodeCacheMode/count/days preferences (default: date, 60 days).
Apply the bound when reading instead of writing, so a preference change
takes effect without a refetch; the full parse cache stays intact so
fetch-more can page beyond the bound. Thread the window through
load/saveFeedsToFile and update tests and task docs.

Bounded Feed Lifecycle

Objective: Bound feed episode storage to a rolling 30-day persisted window (older episodes volatile-only unless downloaded), keep feed loading nonblocking, and surface all load/download activity in a global top-right indicator.

Status legend: [ ] todo, [~] in-progress, [x] done

Tasks

01 — persisted-retention-window → 01-persisted-retention-window.md
02 — volatile-episode-merge → 02-volatile-episode-merge.md
03 — nonblocking-feed-refresh → 03-nonblocking-feed-refresh.md
04 — global-activity-indicator → 04-global-activity-indicator.md

Dependencies

02 depends on 01 (the volatile merge preserves exactly what 01 drops from disk)
03 depends on 01 (debounced persistence layers onto the pruning save path)
03 depends on 02 (incremental per-feed apply consumes the merge helper from 02)
04 depends on 03 (the indicator subscribes to the activity wiring added across refresh/load-more paths in 03)

Exit criteria

After any refresh + save, config.json feeds[*].episodes contains only episodes with pubDate within the last 30 days or episodes marked completed in downloads.json; loading a legacy config prunes stale episodes on first launch.
The volatile episode list and pagination cache are bounded by the same 30-day window as persistence: only in-window episodes are cached/loadable, and everything in-window is (no episode-count ceiling).
A refresh batch never exceeds a fixed fetch concurrency, applies each feed's result as it lands (no Promise.all barrier), and persistence writes are debounced; keyboard input stays responsive throughout.
The top-right indicator is visible iff at least one feed refresh, fetch-more, subscribe fetch, search, or episode download is in flight, hidden otherwise.
bun test and bun run lint pass.
