fix: use consistent git identity for PR test commit hash

The PR_TEST_COMMIT_HASH constant was incorrect because the discovery test
used a different git identity (pr-test@example.com) than the actual
create_pr_test_commit function (test@grasp-audit.local from fixtures.rs).

This caused the same commit content to produce different hashes due to
different author/committer info being embedded in the commit object.

Fixed by updating the discovery test to use the same git identity as
clone_repo() in fixtures.rs, ensuring consistent commit hashes.
