feat(theme-studio): scenes for tmr, wttrin, alert, org-superstar, nerd-icons-completion

tmr shows the list view and tmr-tabulated-view with every column face; wttrin the weather buffer with staleness header, key hints, and the stale modeline lighter; alert one line per severity; org-superstar the bullet swap across levels plus list items; nerd-icons-completion folder icons in the dir face. Phase 4 of the preview run — all 13 small-scene apps now sit in the face-coverage gate.
