test(cli): cover autoCommitPluginMod commit and no-op paths

Browse Source 
autoCommitPluginMod runs `git status --porcelain plugin.mod` then commits if
dirty. Add two cases: dirty plugin.mod produces an "Add plugin.mod" commit,
and a clean state leaves HEAD unchanged. Uses t.Chdir to scope CWD to the
temp repo without polluting parent state.
