Application crashes immediately after quit on macOS

[ndizazzo]

Description

Mesh crashes during application quit instead of shutting down cleanly. macOS shows the system crash reporter after the app is closed.

Environment

• OS: macOS 26.5.1 (25F80)
• Architecture: Apple Silicon / ARM64
• Hardware: Mac16,8
• App version: 0.1.0
• Process: mesh-console

Steps to Reproduce

1. Launch Mesh.
2. Quit the application.
3. Observe the macOS crash reporter.

Expected Result

Mesh exits cleanly without showing a crash report.

Actual Result

Mesh terminates with a crash on quit.

Crash Details

• Exception Type: EXC_CRASH (SIGABRT)
• Termination Reason: Namespace SIGNAL, Code 6, Abort trap: 6
• Application Specific Information: abort() called
• Crashed Thread: Main thread

Impact

The app appears unstable and may fail to clean up resources correctly during shutdown.

Notes

This likely points to shutdown/teardown logic, background task cleanup, or an assertion/fatal error triggered while closing the app.
