The vendored static/vendor/htmx.min.js turned out to be a 33-byte
placeholder, so the hx-get/hx-target/hx-trigger attributes on the
overlay file tree's folder buttons were inert: clicks rotated the
chevron (own JS) but never fetched. Switch the lazy-load to a
~30-line plain-JS handler in static/js/file-tree.js that fetches
button.dataset.filesUrl on first expand and dedupes via dataset.loaded.
Update the spec/plan to match. Route + partial contracts unchanged.

Captures the design rationale for the new overlay-detail Files section
(verify build output, click-to-download for individual files via Flask
send_file, HTMX-driven lazy folder expansion) and the paired
implementation plan that produced it. Adds .superpowers/ to .gitignore
so brainstorm session artifacts never sneak into a future commit.
