Have the review raise recorded state in docs and comments

[GavinLucas]

Documentation and comments keep gaining claims about how things are now: counts, measured figures, what was tested, "currently", and settings held elsewhere. They go stale as soon as anything changes. The callers' instruction files forbid them, but a review that checks each claim against the code passes one that is true on the day, so they were approved round after round.

What changes

• The prompt, in .github/workflows/claude-review.yaml, gains one paragraph for every review, full or delta. It asks the reviewer to:

  • check each line the change adds or edits in docs, code comments, workflow comments and instruction files for recorded state;
  • raise each instance as a maintainability finding, even when it is true today;
  • say where the fact already lives: the command, test or file that answers it, or the commit message or pull request for a record of what was done.

  Rules and their reasons, behaviour that tests hold, and accepted limitations are excluded.

• The README's "The Claude review" section gains a bullet saying so.

Verification

• The workflow YAML parses. The paragraph lands inside the prompt block, and the added lines are plain ASCII.
• actionlint was not run locally. This repository's CI runs it.
• Whether reviews actually raise recorded state shows only once one runs with this prompt. The first will be quaffed's pin-bump pull request: a pull request's own caller workflow decides which pinned version reviews it.

After merging

Tag v1.2.0, then bump the pin in each repository that calls this one.
