Fix: Linux tray quit and zombie icons (#24)

* Fix: Linux tray quit and zombie icons (#23)

- Add before-quit handler to set isQuitting flag
- Change pgrep -x to pgrep -xi for case-insensitive matching on Linux
- Add antigravity-manager to self-kill exclusion filter
- Destroy existing tray before creating new one in initTray()
- Destroy tray in will-quit handler
- Export destroyTray function for cleanup

Fixes #23

Co-Authored-By: Claude Opus 4.5 <[email protected]>

* Fix: Address code review feedback

- Add icon validation before creating tray (isEmpty check)
- Add try/catch around tray.destroy() calls for error handling
- Add try/catch around destroyTray() in will-quit handler
- Add explicit !manager check in Linux process filter for defensive coding
