Using git.init({ "--template": "" }) correctly prevents git from applying any default templates (and hence commit hooks) during repo initialization. Please add a brief inline comment referencing bug #8628 so future maintainers understand the rationale behind this change.

Suggested change

	await git.init({ "--template": "" })
	await git.init({ "--template": "" }) // Prevents default templates/hooks, see bug #8628
