Commits stance: Conventional Commits, gated pushes

Conventional Commits for every commit, in every repo: type(scope): summary. Before pushing, run the repo’s quality gate on HEAD in the exact checkout you will push — whatever its agent instructions name, or what CI runs if they name nothing. Never push to a default branch directly: branch, open a PR, merge through it, unless a repo without a review gate says otherwise. No attribution trailers. AGENTS.md and CLAUDE.md are one file, symlinked, so different agents cannot drift.
