feat(sessions): implement session favorites, tags, sharing, and search (#206)

AGENT 7 Mission - Sessions & History Features

This commit implements the session management features from AMELIORATIONS.md:

## cortex-storage changes:
- Extended StoredSession with is_favorite, tags, and share_info fields
- Added ShareInfo struct for session sharing with expiration
- Created SessionQuery for filtering sessions by:
  - Favorites only
  - Tags (any match)
  - Date range (from/to timestamps, today, this_week, this_month)
  - Working directory
  - Text search (title, id)
  - Pagination (limit, offset)
- Added SessionSort enum for flexible sorting
- Added SessionStorage methods:
  - query_sessions/query_sessions_sync
  - toggle_favorite/toggle_favorite_sync
  - add_tag/remove_tag
  - share_session/unshare_session/get_share_info
  - list_favorites/list_by_tag

## cortex-commands changes:
- Added /favorite command metadata and FavoriteResult type
- Added /share command with duration parsing (7d, 24h, etc.)
- Updated BuiltinRegistry to include favorite and share commands

## cortex-cli changes:
- Extended 'cortex sessions' command with new options:
  - --favorites: filter by favorite sessions
  - --search/-s: search by title or ID
  - --limit/-l: limit number of results
  - --json: output in JSON format

Tests included for all new functionality.
