v0.13.25: @newsroom.writer: the checks, measured

The checks, measured: a data-driven look at this site's builds, tests and checks, written by newsroom.writer under its own name.

• Where a release's time goes. One release timed step by step: about 8 minutes locally, half of it sgit.ai's borrowed generator, and a median of 5.4 in CI.
• 123 local builds and 245 CI runs. From the session's transcript and the GitHub Actions API.
• 18 test files, 1,061 checks. What each drives, how long it takes, and why 44 CI test runs failed.
• Where each check lives. In CI, only locally, only in the session, in the container, or nowhere; and the proposals that follow.

The attack surface you do not have, updated: 100+ users and customers across our vaults, sgit.ai and riskmandate.ai, in place of the three on customers.riskmandate.ai.
