Merge branch 'mm/revision-pure-get-commit-action' into next

The get_commit_action() function has been refactored to be a pure predicate by moving the side-effecting line-level log range folding to simplify_commit(). This ensures that evaluating a commit's action before the walk reaches it does not prematurely mutate its tracked line ranges, making it safer for potential lookahead evaluations. * mm/revision-pure-get-commit-action: revision: make get_commit_action() a pure predicate
