Adds fast unit tests for previously uncovered functions in the daemon package:
- checkDaemonErrorFile: tests reading daemon error files
- StopDaemon: tests error handling for non-running daemons
- KillAllDaemons: tests empty lists and non-alive daemons
- FindDaemonByWorkspace: tests not found case
- discoverDaemon: tests missing socket scenario
- CleanupStaleSockets: tests edge cases (already removed, alive daemon)
- Registry: tests corrupted file handling and unregistering non-existent entries
Coverage improved from 22.5% to 60.0% with only fast tests (<1s runtime).
All new tests work in -short mode and don't start actual daemons.
