  - '📁 Create Override File' when file doesn't exist
  - '📁 Recreate Override File' when file exists
- Added dynamic webview updating after override file creation
- Fixed cog menu not showing reload option when override created during session
- Added updateOverrideFileExists message handler to refresh menu state
- Fixed character encoding issues in webview menu options
