panels/detail.lua now renders the selected module's title, version,
author, markdown description, and per-dep status list with OK/WARN/ERR
glyphs. Dep-list order follows manifest.module::deps[] (L-Q6 load-
order, no re-sort). Whole-list bg-tint is bubbled to ctx.list_tint so
the list panel picks up a yellow/red ambient cue for warn/error
states. Hero strip remains a placeholder until L.5.
Splits rendering into panels/list.lua and panels/detail.lua. List
implements row hit-test, scroll-state, whole-list bg-tint hook for the
dep-conflict UX (L-Q6). Detail renders an empty-state placeholder
until L.4-L.7 fill in title, description, deps, carousel, and launch
button.
