* fix(settings): persist per-model visibility and sibling selector state
The server-side settings sanitizer only allowlisted favoriteModels and
recentModels, so hiddenModels, collapsedModelProviders, recentAgents, and
recentEfforts were stripped on every write to settings.json — per-model
visibility and collapsed-provider state silently reset on every container
redeploy or settings reload.
Add the four missing fields to sanitizeSettingsUpdate:
- hiddenModels: sanitizeModelRefs(..., 1024) — same shape as favoriteModels;
1024 covers dense multi-provider setups while bounding persistence/memory.
- collapsedModelProviders: normalizeStringArray with Array.isArray gate
(matches usageDropdownProviders).
- recentAgents: normalizeStringArray (Array<string> per ui-store).
- recentEfforts: new sanitizeRecentEfforts validating Record<string, string[]>
(shape confirmed in ui-store + addRecentEffort action); trims/dedupes keys
and variants, caps at 128 keys x 5 variants/key (5 matches client slice).
No ui-store version bump or migration: zustand's default merge spreads
persisted state over defaults, so missing fields fall back to [] / {} until
the next toggle. favoriteModels and recentModels are untouched.
Tests: 8 new cases in settings-helpers.test.js using the real
sanitizeModelRefs / normalizeStringArray — round-trips, empty-[] parity with
favoriteModels, garbage rejection, and a full-payload regression test.
* fix: sync model selector settings
