v0.1.4-alpha - Process Cleanup on Exit

What's New

• Process cleanup on app close - Closing the bootstrapper now properly stops all BrainDrive processes (backend + frontend)
• Fixed child process handling - Process group killing ensures npm-spawned vite processes are also terminated
• Retry logic for port cleanup - Handles parent/child process hierarchies reliably

Bug Fixes

• Fixed orphaned processes remaining after closing the bootstrapper
• Fixed frontend (vite) continuing to run after npm parent was killed

Files Changed

• lib.rs - Added exit handler using .on_window_event()
• process_manager.rs - Process group killing + retry logic for kill_process_on_port()
