- JVM extractor now supports --daemon mode: starts once, processes
multiple archives via stdin JSON protocol, eliminating ~5s JVM boot
per archive
- TypeScript side: daemon manager starts JVM once, sends requests via
stdin, falls back to spawning new process if daemon is busy
- Fix extraction progress caching: replaced Object.create(null) + in
operator with Set<string> + linear Array scan — both Map.has() and
the in operator mysteriously failed to find keys that were just set
- Daemon auto-shutdown on app quit via shutdownDaemon() in before-quit
