- feat(vscode-sync): restore auto-sync logic and enable by default

- refactor(settings): remove the VS Code auto-sync toggle from Settings UI
- feat(provider-list): enable auto-sync after "Apply to VS Code"; disable after "Remove"
- chore(prettier): run Prettier on changed files
- verify: typecheck and renderer build pass

- Files
  - added: src/hooks/useVSCodeAutoSync.ts
  - modified: src/App.tsx
  - modified: src/components/ProviderList.tsx
  - modified: src/components/SettingsModal.tsx

- Notes
  - Auto-sync now defaults to enabled for new users (stored in localStorage; existing saved state is respected).
  - No settings toggle is shown; manual Apply/Remove in the list still works as before.
