feat: bring the control plane up to date

Squashes the current state of the internal working tree onto this history.
The two trees had grown apart with no common ancestor, so this is a content
sync rather than a merge, and the published history is preserved rather than
rewritten — a force-push here would break every existing fork and clone to no
benefit.

What lands:

- Waitlist: API route, core module, and migration 0006 alongside game aliases.
- User verification.
- CI, oxfmt config, editor settings.
- Assorted fixes across the API routes and core modules.

The repository's own README, the wordmark and the per-package READMEs are kept
from this side; the internal tree had dropped them and they are what a stranger
arriving here reads first.

The marketing site in the internal tree is deliberately not here. It is a
separate product with its own repo and its own licence, and this repo is the
open one — a closed component does not belong in it regardless of how convenient
the directory looked.
