fix(update): add staging protection to switch_channel

Browse Source 
switch_channel has three destructive code paths (git reset + clean,
git init + checkout --force, and rmtree + ZIP replace) that were
missing the _stage_preserved_items / _restore_preserved_items safety
net already applied to perform_update.

Wrap the channel-specific logic in a try/finally so preserved user
data (settings.json, civitai/, cache/, etc.) is physically moved
outside plugin_root before any git operation and always restored.
