fix: improve screen cleanup and add ghost screen discovery

- 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)
