v3.2.4
Patch release: turn CI green again. No behaviour change.
Fixed
TestRunBrokenWorktreePointerNamesGitCauseasserted that git names the gitdir path in its
error, which macOS git does and Ubuntu's does not (not a git repository: (null)) — so the test
passed locally and failed in CI. It now asserts what v3.2.3 actually guarantees: that git's own
parenthesised cause is carried through at all. The v3.2.3 fix itself is unchanged.
