Subject: [PATCH] CI checkout fetches all history and tags (closes #153)

The checkout step cloned one commit and fetched no tags, so git
describe in script/cibuild gave the image built from a tagged commit
the short commit as its version. .gitea/workflows/check.yml is now the
sneak/prompts copy at 0653579, whose checkout step sets fetch-depth: 0.
That copy also sets persist-credentials: false on the checkout, cancels
the older run on the same branch when a new push arrives, and stops a
run after 20 minutes. The TODO.md status line says the workflow cancels
the older run.
