Test on macOS (profile discovery + native messaging)

[limeflash]

What

Verify Zen Sync works on macOS. The native host profile discovery code has macOS paths but hasn't been tested.

What to test

1. python install.py — creates venv, installs deps, writes manifest to /Library/Application Support/Mozilla/NativeMessagingHosts/
2. Profile discovery finds the correct Zen profile
3. Native messaging works (extension can communicate with native host)
4. Keyring (macOS Keychain) stores the derived key

May need sudo for manifest directory

The macOS manifest path is /Library/Application Support/Mozilla/NativeMessagingHosts/ which may require sudo to create. The installer should handle this or prompt the user.
