ceremony/changelog.d/167.md

### Added

- `changelog_fragment_problem` bounds every entry at 300 normalized
  characters, red on the PR that writes the fragment; the armed guard and
  the assembler inherit the one definition (#167).
- BUILDER.md and CHANGELOG.md state the bound and the split rule: a long
  change ships several short entries, never one long one (#167).
feat: ceremony flips to grouped — changelog.d/shape = grouped, five fragments converted, docs per D6 167/175 gain '### Added', 173/178 '### Changed', 180 '### Fixed' — every bullet byte-identical, headings only (the #158 bar, inverted). CONSUMERS.md names the sentinel and the flip procedure; changelog.d/README.md names the sentinel. 182.md is this PR's own fragment, grouped atop the sentinel it ships.

feat: changelog_fragment_problem bounds entries at 300 characters (#167) One definition in the fragment predicate; changelog-armed reds the PR that writes the fragment and the assembler refuses at release, both by inheritance. Doctrine names the number in BUILDER.md and CHANGELOG.md.
