chore: release v0.2.12

Major UX improvements:
- Changed detail view from full page to drawer (slides from right)
- Moved plugin settings from sidebar to Settings → Plugins (proper pattern)
- Fixed React error #310 by adding defensive String() wrappers
- Fixed syncMessage getter to always return string
- Added safety checks for encryptedData access
- Added error handling for useGet failures

The drawer approach keeps the list visible while viewing details,
matching Headlamp's design patterns. Settings are now properly
located in the global Settings → Plugins section instead of
cluttering the plugin's sidebar navigation.
