docs: make CLAUDE.md the canonical home of the pinned contact-sheet set (#72)

Two files carried the calibration-set membership independently, and the
set changes whenever a new example outclasses a member, so the copies
were guaranteed to drift. CLAUDE.md now owns the list; the prompt points
to it instead of naming members.

 - **Falsification:** every check must be proven to fail once — break the contract, observe the non-zero exit, restore — with the probe and the measured error reported in the PR body. An assertion that cannot fail witnesses nothing.
 - **After gallery regeneration** (`python scripts/build_gallery.py`), read the **generated HTML** character by character — the `<img alt>` text and witnesses callouts in `docs/gallery/index.html` and `docs/gallery/<name>/index.html` — not just `examples/gallery.json`. Precedent: the `teaches.split(".")[0]` bug truncated 14/21 card alts at dotted API paths like `bmesh.ops` while the source JSON looked fine (fixed in PR #68).
