## Problem
All Playwright tests on rh-test were failing due to cloud-specific
initialization blocking test execution:
1. Firebase auth guard waits 16 seconds for auth initialization,
exceeding test timeout (15s)
2. Remote config fetch blocks on /api/features endpoint
3. Snapshot images outdated - rh-test has old snapshots while main UI
evolved
## Solution
**Skip cloud auth guard** (src/router.ts)
- Add `if (!isCloud) return next()` at start of router.beforeEach
- Playwright builds with DISTRIBUTION='localhost', bypassing the guard
- Safe since guard is cloud-only (Firebase, login pages, onboarding)
**Mock /api/features endpoint** (browser_tests/fixtures/ComfyPage.ts)
- Try real backend first, fallback to empty config
- Prevents initialization hang when endpoint unavailable
- Preserves explicit featureFlags.spec.ts test functionality
**Update snapshots from main**
- Pulled 33 snapshot files from main branch
- Fixes snapshot mismatches caused by UI evolution on main
- Includes 3 new snapshots (recordAudio, bypass/mute states)
## Impact
- Playwright tests can now initialize and run on rh-test
- Cloud functionality unchanged (fixes only affect
DISTRIBUTION='localhost')
- No production behavior changes
