Initial commit: NAUT torrent web UI with stubbed server

Advanced torrent client web UI aimed at power users, with a
zero-dependency Node stub server (built-in http + SSE) serving live
mock data.

- Dense sortable/multi-select torrent grid with live updates
- Detail panel: General/Trackers/Peers/Content/Pieces (resizable)
- Sidebar filters: status, categories, tags, trackers
- Create/delete categories and tags (sidebar + right-click)
- Add via magnet or client-side-parsed .torrent upload
- RSS, integrated search, and read-only engine views
- Hand-drawn SVG icon set, dark theme, keyboard shortcuts
