fix: add operation context to error handling

Restore error message in quickUpdate to provide operation context.
Users now see:
1. '✗ Quick update failed' (what operation failed)
2. 'Installation failed: [details]' (why it failed from caller)

This provides better UX than generic 'Installation failed' alone.
