docs(yazi-remake): mark task 07 blocked, file task 04 blocker for player/search panes

The verification gate found that Task 04's core deliverable was never
implemented: Player and Search pages are not routed through <YaziPaneRow>,
so Player renders a single full-width column and Search's three columns
sit at equal thirds (31/32/31) instead of the target 1:3:3 ratio
(~14/43/43).

- Mark task 07 status BLOCKED with a pointer to the blocker evidence
- Add 07-blocker-task-04-player-search.md documenting the missing
  implementation, evidence (player/search harness frames), failing exit
  criteria, and a fix plan for the task 04 do-over

+# 07-blocker — Task 04 (Search + Player) never converted to YaziPaneRow

+## Problem
+
+Task 04 (`04-fit-search-and-player-panes.md`) is marked complete, but its
+core deliverable was never implemented:
+
+> - `src/pages/Player/PlayerPage.tsx` — rendered through `<YaziPaneRow>`
+> - `src/pages/Search/SearchPage.tsx` — rendered through `<YaziPaneRow>`
+
+`grep -rn "YaziPaneRow" src/pages/Search src/pages/Player` → **0 files**.
+
+## Evidence (from task 07 harness walk-through, 100×30)
+
+### Player ❌
+
+`src/pages/Player/PlayerPage.tsx` renders a single full-width
+`<scrollbox>` (now-playing transport + controls). No parent pane, no preview
+pane. Frame `.harness/player-current.txt`:
+
+```
+│ Now Playing                                                  0:00 / 0:00 (0%) │
+...
+│ │ │[Prev]│ │[Play]│ │[Next]│   Vol 70%  Speed 1x  ... │ │
+```
+
+Expected (task 04 + feature exit criteria): `blank | transport | notes` at
+1/7 : 3/7 : 3/7.
+
+### Search ⚠️ ratio wrong
+
+`src/pages/Search/SearchPage.tsx` renders three custom `<box flexGrow={
+PANE_RATIO.* }>` columns but **omits `flexBasis={0}`**, so Yoga distributes
+space by natural content width (the input box is `width={28}`). Measured
+column widths at 100 cols: **31 / 32 / 31** (equal thirds), NOT the target
+**~14 / 43 / 43** (1:3:3).
+
+`<YaziPaneRow>` exists precisely to set `flexBasis={0}` per column and force
+the exact 1:3:3 ratio regardless of content (see its header comment). Routing
+Search through it fixes the ratio for free.
+
+## Why not patched in task 07
+
+Task 07 is explicitly the verification gate. Its notes:
+
+> - This is the gate for the whole feature — do not mark done if any criterion
+>   fails; open a blocker task instead
+> - If the harness reveals a visual regression (e.g. parent collapses, ratios
+>   off), file it against the responsible task (02 or 03) rather than
+>   patching here
+
+This is a missing implementation in task 04, not a regression in 02/03, so the
+responsible task is 04. Patches belong there.
+
+## Failing exit criteria
+
+- "All tabs render three stable columns at 1/7 : 3/7 : 3/7" — Player fails
+  (not 3 columns); Search fails (wrong ratio).
+- "`5` → Player: blank|transport|notes at 1:3:3" — fails.
+- "`4` → Search: query|results|detail at 1:3:3" — 3 columns yes, ratio wrong.
+
+## Fix plan (task 04 do-over)
+
+1. `src/pages/Player/PlayerPage.tsx` — wrap the existing transport JSX in a
+   `<YaziPaneRow current={transport} parent={undefined} preview={notes} />`.
+   Parent should fall through to the primitive's muted `—` placeholder (it
+   already keeps its 1/7 slot when blank). Preview = episode description /
+   waveform (currently inline under "Now Playing"). Keep `PlayerPaneCount=1`
+   (the visible columns are a render concern; only current=0 is focusable).
+2. `src/pages/Search/SearchPage.tsx` — replace the three custom `<box
+   flexGrow={PANE_RATIO.*}>` columns with a single `<YaziPaneRow
+   parent={queryInput+recent} current={resultsList} preview={detail}
+   focused={!inputFocused() ? /* results */ : false} />`. Keep the
+   `inputFocused` effect so the Shell yields keys to the native `<input>`
+   when the query pane is focused — note `inputFocused` is a Search-owned
+   signal; YaziPaneRow's `focused` prop only drives the accent ring + scroll
+   focus, which for Search can stay on the current (results) column.
+3. Remove the now-dead custom ratio code from both files after the swap.
+4. Re-run: `grep -rn YaziPaneRow src/pages/Search src/pages/Player` → 2 files;
+   `bun run build`; `bun test`; harness walk-through: Player shows 3 cols,
+   Search cols measure ~14/43/43.
+
+## Verification gates (re-run task 07 after fix)
+
+- `bun run build` → "Build complete"
+- `bun test` → 0 fail
+- harness:
+  - Player frame has 3 bordered columns (parent `—`, current transport,
+    preview notes/placeholder) at 1:3:3
+  - Search frame columns measure ~14/43/43
