fix(quick-actions): improve Open Repository in Browser error handling

- Add await to shell.openExternal call to ensure proper async handling
- Show toast notification when no remote URL is found for the repository
- Add error handling with toast feedback for any failures
- Update tests to verify toast notifications are shown on error

Fixes issue where the command didn't provide feedback when failing.
