/favorite
Pin this session as a favorite so you can find and reopen it later. Favorites are stored in your own private GitHub gist, so they follow you across machines.
Run from the repo root, passing any text after /favorite as the label:
node scripts/session-favorites.mjs pin "$LABEL"
Then relay the script's confirmation. If the developer gave no label, run pin with no argument. Backed by the favorite-session skill; companion commands: /favorites, /open-favorite, /unfavorite.
