Correct Step 5: Move misplaced files out of deployment/

After reviewing Step 5, found 5 files that don't belong in deployment/:

Moved to better homes (keeping original filenames):
- turbolinks.md → building-features/
  (feature integration, not deployment)
- updating-dependencies.md → misc/
  (generic maintenance, temporary holding)
- rails-engine-integration.md → advanced-topics/
  (advanced setup, temporary holding)
- convert-rails-5-api-only-app.md → migrating/
  (prerequisite migration)
- rails_view_rendering_from_inline_javascript.md → api-reference/
  (API reference)

Created temporary folders for review later:
- misc/ (for orphaned generic files)
- advanced-topics/ (for advanced setup scenarios)

Deployment now focused on actual deployment (7 files):
- Production setup (4 files)
- Troubleshooting (3 files)

See Decision 4 & 5 in ia-redesign-live.md for rationale.
