The uups-bank-demo wave's SDD records (ledger, six task briefs and reports, review diffs) and the brainstorm design mockups were git-ignored, so they existed only on one sandbox VM and reached no remote — this repo had no remote at all until now. Removes `.superpowers/` from .gitignore and the `*` .gitignore the superpowers plugin writes inside .superpowers/sdd/; the second blocks the directory even with the first removed. Excluded as ephemeral local-server state, and now ignored by name: .last-port, .last-token (a 64-char session token for a brainstorm server on a port that is long gone), and the per-session state/ directories.
