v1.5.0: Cleaner process shutdowns

This release improves how pitchfork stops daemons and their child processes, making shutdown more reliable and eliminating orphaned processes.

Highlights

• Process group-based shutdown — Pitchfork now spawns each daemon in its own process group via setsid() and uses killpg() to signal the entire group at once. This replaces the old approach of walking /proc to find children, which was prone to race conditions where a child could fork between the scan and the kill. Daemons that spawn multiple children (e.g. npm run dev) will now shut down cleanly and atomically. #239

• SIGKILL escalation after SIGTERM — When a daemon doesn't respond to SIGTERM, pitchfork now automatically escalates to SIGKILL to ensure the process is terminated. No more stuck daemons that ignore graceful shutdown signals. #238 — thanks @gaojunran!
