feat(daemon): add stealth injection orchestrator (Task 17)

- Create stealth/index.ts: applyStealth() calls all 6 injection modules
  in correct order (initScript before nav, page.route after page)
- Update browser-manager.ts: call applyStealth in createPage before goto
- Constructor now accepts profileId (default 'desktop-chrome') or profile object
- Update daemon src/index.ts: re-export stealth orchestrator, getProfile,
  humanClick, humanType, humanScroll, injectHeaderStealth
