Replaced every bottom-of-section 'See also:' block with inline
Org-mode file: links at the first natural mention in body text.
All 29 files across the economics directory now use wiki-style
inline cross-references rather than standalone reference blocks.
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
