post-commit skipped on CHERRY_PICK_HEAD, which git leaves on disk while
the hook runs, so a clean pick never rebuilt. A rebase has no hook that
fires once at the end, because post-commit and post-checkout skip while
rebase-merge/ exists.
Drop the CHERRY_PICK_HEAD check. For a range pick or revert, skip every
step but the last and diff from sequencer/head, so one rebuild covers
the range; ignore a stale sequencer/ left by git reset --hard. Add a
post-rewrite hook that rebuilds on rebase.
