Before

release-please refreshes the release PR -> CHANGELOG.md gains an entry with `*` bullets -> biome ci formats markdown -> checks / check red

$ bun x biome ci --error-on-warnings .
CHANGELOG.md format
  x File content differs from formatting output
Found 1 error.
error: script "lint" exited with code 1

After

release-please refreshes the release PR -> CHANGELOG.md is not formatted -> checks / check green

$ bun x biome ci --error-on-warnings CHANGELOG.md      (the release PR's CHANGELOG.md)
Checked 1 file in 7ms. No fixes applied.

How

• One override in biome.local.jsonc turns the formatter off for CHANGELOG.md, the file release-please owns.
• The managed biome.json is untouched; the same exclusion belongs in the fleet layer eventually.

Proof

• Control: the release PR's CHANGELOG.md fails biome ci without the override and passes with it.
• Gate: bun run lint green, 1037 files.

Technical details

• Release PR chore(main): release 3.0.0 #58 does not re-run on this merge. A chore commit refreshes no release notes, so close and reopen chore(main): release 3.0.0 #58 to re-run its checks against the new main.
• Main's CHANGELOG.md keeps its formatted history. release-please only prepends, so older entries stay as they are.
• Files: biome.local.jsonc.
