commit

Writes structured git commit messages following Conventional Commits. Use when the user asks to commit, says "commit this", mentions writing a commit message, or when git commit context is present. In the chain-hub monorepo, commits touching cli/ or apps/hub/ MUST use conventional types (feat, fix, revert, refactor, chore, docs, test). Only feat/fix/revert update cli/CHANGELOG.md via git-cliff. Produces type(scope): subject format with optional body, roadmap refs, and breaking change notation — cross-editor.
