Upstream only listed the vercel/claude-hud/find-skills/web-design files
individually, so newly added files under those dirs still showed up as
untracked. Ignore the whole directory for every skill that does not
exist upstream.

BMSv4_pincfg and cubemx-min-prj were removed upstream but are still
used on this machine; keep them on disk and untracked. Also ignore
.stfolder (syncthing metadata) and .claude.
