Convert cross-references from [[id:uuid]] to [[file:name.org]]

All 117 inter-node links now use [[file:node-name.org][title]] format
which renders as clickable hyperlinks in both Emacs (C-c C-o) and
web-based org renderers (Gitea, GitHub). Each node retains its :ID:
UUID property for Emacs org-roam database features (backlinks,
capturing, node-find).

Prev format: [[id:uuid][title]] — Emacs only, dead text on web
New format:  [[file:name.org][title]] — works everywhere
