/**
 * Throws on git failure with the real stderr attached. Use this when the
 * caller needs to distinguish hook rejection / GPG signing failures / LFS
 * lock errors from a successful no-op. Callers should pre-check
 * `hasUncommittedChanges` to avoid the "nothing to commit" rejection
 * (which `git commit` exits non-zero for).
 *
 * Returns `null` (rather than throwing) when the commit itself succeeded
 * but `git rev-parse HEAD` failed transiently — by contract the diff is
 * no longer in the working tree, so callers must NOT report it as such.
