Grissiom.GuRui 659a41a6cc feat(extensions): add --force flag to extension add for overwrite reinstall (#2530)
* feat(extensions): add --force flag to extension add for overwrite reinstall

Add --force support to `specify extension add` that allows overwriting
an already-installed extension without manually removing it first.

- install_from_directory() and install_from_zip() accept force=True,
  automatically calling remove() before installation
- The --force CLI flag works with all install modes (--dev, --from URL,
  bundled, and catalog)
- Config files (*-config.yml) are preserved across force reinstall
- Error message suggests --force when extension is already installed
- 6 new tests covering unit and CLI force reinstall flows

* fix: address PR review feedback on --force implementation

- Remove unused `backup_config_dir` variable assignment (Ruff F841)
- Defer `remove()` until after `_validate_install_conflicts()` to prevent
  data loss if validation fails mid-reinstall
- Use `TemporaryDirectory` instead of `NamedTemporaryFile` in ZIP test
  to avoid Windows file-locking failures

* fix: only restore config backup when --force actually triggers a remove

When --force is used but the extension is not already installed, the
backup restore/cleanup should not run. Previously it could resurrect
stale config files from a previous removal and delete the backup
directory unnecessarily.

* fix: address Copilot review feedback on --force implementation

- Clear stale backup dir before remove() so only fresh backups are restored
- Restore only config files (*-config.yml, *-config.local.yml) from backup
- Remove trailing \n from --force console message (console.print adds newline)

* fix: handle non-directory paths in backup cleanup/restore

- Use is_dir() before rmtree/iterdir on backup path to avoid crashes
  when .backup/<id> exists as a file or symlink
- Remove unused manifest1 variable in test_install_force_reinstall

* fix: handle symlinks in backup cleanup/restore and correct CLI message

- Check is_symlink() before is_dir() in backup cleanup and restore:
  Path.is_dir() follows symlinks (returns True for symlink-to-dir) but
  shutil.rmtree() raises OSError on symlinks. Handle symlinks by
  unlinking them instead.
- Skip symlink entries during config file restore.
- Change --force dev-install message from "Reinstalling" to
  "Installing [...] (will overwrite if already installed)" because
  --force also works for first-time installs.
