* [b7174c1a] docs(frontend): rename hooks.md heading back to match backend's item-12 citation and correct suppression counts (#763)

Round-2 pr_gate review of PR #758 found two issues in docs/frontend/hooks.md's
suppression-audit section: the heading had drifted from "Mount-only effect
audit" to "Frontend lint-suppression audit", breaking backend's item-12
citation in docs/backend/lint-suppression-reconciliation.md which cites this
section by its original title; and the counts sentence wrongly implied
backend's doc tracks a separate ~24-item remainder outside this frontend
suppression, when backend's doc is actually the canonical 32-item ledger
that already includes this one as item 12. Renamed the heading back verbatim
(confirmed via repo-wide grep that no other file references the old heading
or its anchor slug) and rewrote the sentence to describe backend's doc as
the canonical reconciliation ledger and this section as the narrative
writeup for item 12 within it.

 No manual guard is needed before calling the hook — the `enabled: !!taskId` guard is built in and prevents wasted API calls and race conditions.

+**Scope: this section is a frontend-only accounting.** It covers lint suppressions (`eslint-disable`, `@ts-ignore`, `@ts-expect-error`) found in `panel/` alone — it is not the company-wide suppression ledger. Backend's [`docs/backend/lint-suppression-reconciliation.md`](../backend/lint-suppression-reconciliation.md) is the canonical 32-item reconciliation (2 waived + 9 framework-exempt + 2 fixed-at-source + 19 already-resolved) covering every suppression Sentinel's `no_lint_suppressions` hygiene scan originally flagged company-wide; this single frontend `eslint-disable` is already accounted for there as item 12, and this section is the detailed narrative writeup for that one item.
+
+A direct grep of `panel/` for `eslint-disable`, `@ts-ignore`, and `@ts-expect-error` (excluding `node_modules`) historically found exactly **one** frontend suppression, documented below. It was fixed at the source in a later round (see disposition below); re-running the same grep against `panel/` today returns zero hits.

+### `eslint-disable` formerly in `journals-view.tsx`, now removed — fixed at the source, no waiver needed
 
 Sentinel's `no_lint_suppressions` hygiene scan flagged `// eslint-disable-next-line react-hooks/exhaustive-deps` guarding the mount-only localStorage-restore effect in `JournalsViewContent` (`panel/src/components/journals/journals-view.tsx`). That effect restores the `agent`/`type`/`task` filters saved from a prior visit into the URL, but only on a fresh `/agents?tab=journals` visit that carries no query params yet — it must run exactly once per mount, never again, or it would clobber a later intentional "clear filters" action with stale saved state.

 The suppression was removed by replacing the empty `[]` dependency array with a `useRef` mount-guard:
