Add parent process monitoring to detect when bit server becomes orphaned (PPID changes to 1). This can happen when the parent process crashes or is force-killed. The server now shuts down gracefully in these cases instead of running indefinitely and exhausting FSEvents/file descriptors. Includes debug logging of parent process info for troubleshooting.

Pull request overview
This PR adds automatic shutdown functionality for orphaned bit server processes by monitoring the parent process ID (PPID). When the parent process (typically VSCode) crashes or is force-killed, the server detects this and shuts down gracefully instead of running indefinitely and exhausting system resources.
Key Changes:
- Added parent process monitoring that checks every 5 seconds if the PPID has changed to 1 (indicating orphan status on Unix-like systems)
- Implemented cross-platform process info retrieval using
execSyncto log parent process details for debugging - Used
unref()on the monitoring interval to prevent it from keeping the Node.js process alive unnecessarily
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
- Skip orphan detection on Windows (PPID doesn't change to 1) - Replace deprecated WMIC with PowerShell Get-CimInstance - Improve documentation to clarify platform limitations
