ci: bump the ruff pin with the dependency, and guard the drift

The dependabot bump moved pyproject's ruff pin to 0.16.1, but nothing else
followed it, so the repo asked for three different versions at once:

- pyproject.toml said 0.16.1 (the bump)
- uv.lock still resolved 0.15.20 (dependabot did not update it)
- .github/workflows/ci.yml installed 0.15.14 by its own literal pin

The lint job never reads pyproject, so CI kept linting with 0.15.14 and
reported this PR green without 0.16.1 ever running. The ci.yml pin had
already drifted from pyproject before this bump, under a comment saying to
keep them identical.

- ci.yml: pin 0.16.1 to match pyproject.
- uv.lock: regenerated so the locked resolution agrees.
- test_ruff_pins_match: assert ci.yml and pyproject stay equal, so the next
  bump that touches only one of them fails loudly instead of passing blind.
- extend-exclude '*.md': 0.16 began formatting Python inside markdown
  fences, taking the formatter from 199 files to 295 and reflowing
  hand-aligned example code in docs/rfcs/002 and three website pages.
  Excluding docs keeps this a version bump rather than a silent
  documentation reflow, and restores the exact file scope the project has
  always formatted.

Verified with 0.16.1 actually installed: ruff check and ruff format --check
both clean over the same 199 files, full suite green (3669 passed).
