- Extract all migrateDeprecatedValue logic from individual settings into centralized settingsMigration.ts
- Remove migrateDeprecatedValue from SettingParams interface and coreSettings definitions
- Simplify settingStore by removing tryMigrateDeprecatedValue function
- Ensure migrations run after loadSettingValues() for clean initialization flow
- Update tests to reflect new migration approach
This refactor centralizes all setting value migrations in one place, making them easier to maintain and avoiding timing issues with settings that don't exist yet.
