The post-commit hook re-invokes fix-consistency, which commits writeback
changes, which re-triggers the hook — causing exponential process spawning.
Fix: pass GIT_CUSTODIAN_SYNC=1 in the env for all writeback git commits.
Update the post-commit hook (not tracked by git) to exit early when this
variable is set.
Also remove the --no-verify flag that was added as a failed attempt (it
only skips pre-commit/commit-msg, not post-commit hooks).
