Pull request overview

This PR adds user-facing affordances to remove individual entries from the sidebar's Recent Files list, addressing Bug #234. The implementation includes context menu actions on all platforms and iOS swipe gestures, with comprehensive persistence updates to keep the MRU list synchronized across app sessions.

Key Changes

• UI Enhancement: Added "Remove from Recents" context menu (all platforms) and swipe actions (iOS) to each sidebar entry for discoverable deletion
• Controller & Service Updates: Exposed removeRecent(_:) API on DocumentSessionController and optimized RecentsService to conditionally persist only when records actually change
• Test Coverage: Added unit test verifying removal persistence behavior through the full stack from controller to session snapshots

The generated task report contains malformed task IDs with special characters and backticks (e.g., "#10", "#15.", "#15", "#220", "#222", "#222`)", "#231**:", "#232**:", etc.). These appear to be parsing artifacts from @todo comments in code or documentation that include non-alphanumeric characters. The task ID parser should be hardened to extract only valid task identifiers and ignore punctuation that follows the ID.
