108f63b4f2 fix(browser-pool): replace queue with thread-local storage to fix Playwright cross-thread crash (#53)
Playwright's sync API binds its greenlet event loop to the creating thread.
Sharing pre-warmed slots across threads caused "cannot switch to a different
thread" panics under uvicorn. New design: each worker thread owns its own
Playwright instance created lazily on first fetch_html() call. A registry
dict keyed by thread-id lets stop() close all slots at shutdown. Removes
ThreadPoolExecutor warmup and idle-cleanup daemon thread entirely.

89d3862f62 feat(monitor): background saved-search monitoring with watch alerts (#12)
Some checks failed
CI / Python tests (push) Has been cancelled
CI / Frontend typecheck + tests (push) Has been cancelled
Mirror / mirror (push) Has been cancelled
Release / release (push) Has been cancelled
Backend:
- Migrations 013-015: eBay user tokens, monitor settings on saved_searches
  (monitor_enabled, poll_interval_min, min_trust_score, last_checked_at),
  watch_alerts table with UNIQUE dedup on (saved_search_id, platform_listing_id),
  active_monitors registry for cross-user polling
- WatchAlert model + store methods: upsert_alert, list_alerts, dismiss_alert,
  count_undismissed_alerts, dismiss_all_alerts, list_active_monitors
- monitor.py: run_monitor_search() using TrustScorer.score_batch(); should_alert()
  with BIN/auction/partial-score logic (auction window = 24h, partial +10 buffer)
- PATCH /api/saved-searches/{id}/monitor, GET /api/alerts, POST /api/alerts/*/dismiss
- Background polling loop at startup (asyncio.to_thread every 60s check cycle)
- ebay/adapter.py: enrich_seller_trading_api() via Trading API GetUser (OAuth token)
- nginx: raise proxy_read_timeout to 120s for slow eBay search responses

Frontend:
- AlertBell component: bell button + unread badge + panel with dismiss/clear-all;
  polls /api/alerts every 2 minutes; aria-live announcement on count change
- alerts.ts Pinia store: fetchAlerts, dismiss, dismissAll
- SavedSearchesView: monitor toggle + poll interval + min trust score controls
- SettingsView: eBay OAuth connect/disconnect section
- AppNav: AlertBell wired for logged-in and local-tier users

Tests: 24 monitor tests (should_alert branches, store alert CRUD, run_monitor_search
with mocked adapter); fix browser_pool test assertions for new wait_for_* params.
