Refactor UI into separate CSS/JS, add help modal and HELP.md

- static/index.html: reduced to 127-line HTML shell
- static/style.css: all styles extracted (~900 lines) + help modal styles
  + shared markdown rendering for file-preview and help-modal-body
  including tables (previously missing)
- static/app.js: all JS extracted (~900 lines) + help modal fetch/render
- index.html: adds ? help button + help modal HTML
- inara/HELP.md: comprehensive reference doc covering all features,
  keyboard shortcuts, API endpoints, memory system, planned items
- routers/files.py: HELP.md added to ALLOWED set
- context_loader.py: HELP.md loaded at tier 2+ (after PROTOCOLS.md)
  so Inara can reference it when helping Scott with the interface
