Merge branch 'integration/sw-home-menu' into feature/sw-home-menu

Integrate the SW home (logo) menu into SWHeader for SW general mode only.
SW viewer mode code and stories are unchanged.

- Resolve conflicts: keep both sw-home-menu and sw-viewer exports;
  renumber AI docs (catalog viewer 8->9, patterns home menu 7->8,
  design rules home menu 11->12)
- SWHeader: start the home menu after the file name when it sits
  inside controls, so the file name stays visible
- AI guides: mark home menu as general-mode only; forbid it in viewer
  mode (AI_USAGE, catalog, design rules, patterns, VIEWER.md, AI_GUIDE)
- Tests: ignore wildcard identifiers in ai-docs check; update expected
  Storybook SW titles (SW/Tool removed, SW/Viewer added)
- Add merge QA report docs/sw/sw-home-menu-merge-2026-10-19.md
