feat: implement all P0 UX improvements - visual hierarchy, readable previews, search filter, default session
P0.1: Visual Hierarchy for Tiles
- Backend: Added last_activity_at to GET /api/sessions by querying tmux list-sessions -F '#{session_activity}'
  Updated sessions.py with tuple return from enumerate_sessions and activity cache
  Updated main.py poll loop to populate both session endpoints with activity data
- Frontend: sessionPriority() now returns 'active' (< 5 min) in addition to 'bell'/'idle'
  Added .session-tile--active (accent left border) and .session-tile--stale (dimmed styling) CSS classes
  Updated session-tile.js and sidebar-item.js to apply priority-based classes
- Fixed P4 hover fade bug: removed opacity:0 rule on .session-tile:hover .tile-meta

P0.2: Readable Tile Previews
- Wired --preview-font-size CSS variable (was set by JS but never consumed by CSS)
  Changed default from 11px to 12px with line-height 1.2 (was 1.0)
- Reduced preview line count from 20 to 12 lines for better readability at larger size

P0.3: Search/Filter Bar
- New <search-filter> Lit component with live input, match count, and clear button
  Replaces empty filter-bar div in index.html with functional search component
  Integrated into renderGrid() for live filtering and bindStaticEventListeners() for re-render on input

P0.4: Default Session / Quick-Resume
- Updated restoreState() to fall back to default_session setting when no active_session in server state
  Added existence check before opening to prevent errors on non-existent sessions

Files changed: sessions.py, main.py, app.js, style.css, session-tile.js, sidebar-item.js, utils.js, index.html
New files: search-filter.js (Lit component)
Test updates: test_api.py, test_frontend_css.py, test_integration.py, test_sessions.py

All 1306 tests pass.
