fix(intelligence): make page content scrollable inside Brain card (#4332)

 - **Queue self-heal retries transient failures only** — `memory_queue/scheduler.rs` calls `store::requeue_transient_failed` every 3h (excludes `failure_class = 'unrecoverable'` so bad keys/budget don't retry-loop). Full reset stays manual via `memory_tree_retry_failed` RPC.
 - **`openhuman.memory_sources_reconcile` RPC** — Reports per-scope raw coverage `{total_raw_files, covered, pending}`; `execute: true` spawns background incremental rebuild. Same reconcile auto-runs after every sync via `check_and_rebuild_tree`.
 - **L0 seal gate is token-only by design** — `should_seal` has NO sibling-count fallback at L0 (docs used to lie about this); small buffers seal via the 3-hourly `flush_stale` path. L≥1 gates on `SUMMARY_FANOUT` (10) — an L1 buffer holding <10 summaries is healthy, not stuck.

+## Intelligence page scroll ownership (#4267)
+
+- **`app/src/pages/Intelligence.tsx` is rendered ONLY by `Brain.tsx`** (`/settings/intelligence` redirects to `/brain?tab=intelligence`), inside a card with `h-full overflow-hidden` (`Brain.tsx` ~line 255). A code comment there asserts the embedded panels "own their own scroll directly" — true for the sibling `PanelPage`/`PanelScaffold` panels (MemoryDataPanel etc.), but Intelligence previously returned a bare `<div className="z-10 relative">` with NO height/scroll, so its content overflowed the card and was clipped with no scrollbar.
+- **Fix pattern (matches `PanelPage`)**: root `flex h-full min-h-0 flex-col` → pinned `SettingsHeader` wrapper (`flex-shrink-0`) → body `min-h-0 flex-1 overflow-y-auto` wrapping ChipTabs + the content card. `ToastContainer`/`ConfirmationModal` stay as siblings OUTSIDE the scroll region. The scroll body carries `data-testid="intelligence-scroll"` for the regression test.
+- **Gotcha for any panel embedded in Brain's Knowledge/Memory card**: it must own its own vertical scroll (the card is `overflow-hidden`). Don't rely on a parent scroll — there isn't one.
