Adding a New User Setting

When adding a new toggle/setting to the Settings page:

1. Add the field to UserSettingsSchema in src/lib/schemas.ts
2. Add the default value in DEFAULT_SETTINGS in src/main/settings.ts
3. Add a SETTING_IDS entry and search index entry in src/lib/settingsSearchIndex.ts
4. Create a switch component (e.g., src/components/MySwitch.tsx) - follow AutoApproveSwitch.tsx as a template
5. Import and add the switch to the relevant section in src/pages/settings.tsx
6. Adding a field to DEFAULT_SETTINGS breaks the inline snapshots in src/__tests__/readSettings.test.ts. After confirming the diff is just your new field, regenerate them with npm test -- -u.

If the setting adds a built-in default, update the inline snapshots in src/__tests__/readSettings.test.ts; otherwise npm test will fail with default settings snapshot mismatches.

For settings whose default can be overridden remotely:

• Prefer leaving the raw stored field unset until the user explicitly changes it, then compute the effective value as stored value ?? remote default ?? built-in fallback. Do not persist remote-applied defaults into user-settings.json.

For schema-validated settings:

• Assume UserSettings and other parsed schema types have already normalized field types. Prefer idiomatic boolean checks like settings?.flag && !settings.hidden over defensive literal comparisons like settings?.flag === true && settings.hidden !== true, unless you are intentionally handling raw unvalidated persisted data before schema parsing.
