scripts/release.py AUTHOR_MAP is greped by the Contributor Attribution Check to resolve a commit author's email -> GitHub username. Add huangsen365@gmail.com -> huangsen365 so this PR's commits pass the check. (This commit originally also carried a gateway race-test flake fix; that edit is now dropped because main independently hardened the same test with a superior server._sessions snapshot/restore isolation, making ours redundant.)
