- Pre-compile ANSI escape and whitespace regex patterns in respawn controller
- Pre-compile screen pattern regex for screen list parsing
- Batch ps and pgrep calls in getScreensWithStats() for multiple screens
- Reduces subprocess spawns from O(2n) to O(2) for n screens

- killScreen now uses 4 strategies for reliable cleanup:
1. Kill all child processes recursively (SIGTERM then SIGKILL)
2. Kill entire process group (-PID) to catch orphans
3. Kill screen by name (screen -X quit)
4. Direct SIGKILL as final fallback
- Refresh screen PID from screen -ls before killing (handles stale PIDs)
- reconcileScreens now discovers unknown claudeman screens from screen -ls
This prevents "ghost" screens that persist after screens.json is lost
- restoreScreenSessions handles newly discovered screens
The rapid session creation test now fails because discovery is working -
it finds screens that weren't killed fast enough (test timing issue)

- killScreen now finds and kills all child processes before quitting screen
to prevent claude processes from becoming orphaned (the main bug)
- Add cleanupSession() method for comprehensive resource cleanup:
respawn controllers, timers, batches, event listeners, and sessions
- Fix /api/run endpoint to cleanup sessions after completion
- Fix /api/quick-start error path to cleanup on failure
- Add MAX_CONCURRENT_SESSIONS (50) limit to prevent unbounded growth
- Update CLAUDE.md with improved documentation

GNU screen creates blank space at the top when initializing sessions.
This is now handled after attaching to the screen:
- Claude sessions: emit clearTerminal event after 100ms, client clears xterm
- Shell sessions: send 'clear' command after 100ms
Also updates CLAUDE.md with documentation of the fix.

- Monitor panel now opens by default on webapp start
- Replace "Reconcile" button with refresh icon (↻)
- Change close button to toggle (▼/▲) for collapse/expand
- Preserve session display names when saving screen info
- Use stored name when restoring sessions (no more "Restored:" prefix)

Add screen session management infrastructure:
- ScreenManager class to create, track, and kill GNU screen sessions
- Persistence of screen sessions to ~/.claudeman/screens.json
- Process stats collection (memory, CPU, child count)
- Reconciliation to detect dead/orphan screens
New API endpoints:
- GET /api/screens - list screens with stats
- DELETE /api/screens/:sessionId - kill screen
- POST /api/screens/reconcile - find dead screens
- POST /api/screens/stats/start|stop - control stats polling
New Process Monitor panel:
- Slide-up panel with real-time stats (2s updates)
- Shows memory, CPU, child processes per screen
- Kill button for each screen session
- Reconcile button to clean up dead screens
