Remove the config file location display from settings dialog to simplify
the user interface. Users who need to access the config file can still do
so through the advanced settings section.
Changes:
- Removed ConfigPathDisplay component and its usage
- Removed configPath and openConfigFolder from useSettings hook
- Removed configPath and openConfigFolder from useSettingsMetadata hook
- Removed related i18n keys: configFileLocation, openFolder
- Updated settings dialog to remove the config path display section
This simplifies the settings UI while maintaining access to config
directory management through the advanced settings tab.
Before optimization:
- useSettings.ts: 516 lines (single monolithic hook)
After optimization:
- useSettingsForm.ts: 158 lines (form state management)
- useDirectorySettings.ts: 297 lines (directory management)
- useSettingsMetadata.ts: 95 lines (metadata management)
- useSettings.ts: 215 lines (composition layer)
- Total: 765 lines (+249 lines, but with clear separation of concerns)
Benefits:
✅ Single Responsibility Principle: each hook focuses on one domain
✅ Testability: independent hooks are easier to unit test
✅ Reusability: specialized hooks can be reused in other components
✅ Maintainability: reduced cognitive load per file
✅ Zero breaking changes: SettingsDialog auto-adapted to new interface
Technical details:
- useSettingsForm: pure form state + language sync
- useDirectorySettings: directory selection/reset + default value computation
- useSettingsMetadata: config path + portable mode + restart flag
- useSettings: composition layer + save logic + reset logic
