Adds a new Content Tree tab (default) to rData that indexes all Automerge
docs in a space. Includes /api/content-tree endpoint, folk-content-tree
web component with search, tag filtering, sort modes, expand/collapse,
and demo data fallback. Analytics moves to second tab.

All 22 module directories under modules/ now match their module IDs
(e.g. modules/cart → modules/rcart, modules/canvas → modules/rspace).
Updated all import paths, vite build config, HTML template asset refs,
docker-compose standalone commands, and .gitignore accordingly.
