Adds a serial-lane ILM integration regression test that pins the local-first ordering contract established by rustfs#3491, where `expire_transitioned_object` deletes local metadata BEFORE any remote tier cleanup so a concurrent GET can never observe live local metadata pointing at an already-removed remote tier version (user-visible `NoSuchVersion`). `serial_tests::test_expire_transitioned_object_never_races_concurrent_get` in `crates/scanner/tests/lifecycle_integration_test.rs`: - Transitions an object to a mock warm tier, then runs a tight concurrent GET loop while calling `expire_transitioned_object`; every GET must return a full, correct body or a clean object/version-not-found -- never a tier-fetch failure. - Deterministic ordering assertion (revert-proof): immediately after expiry the remote tier object is still present and the mock recorded zero remote `remove` calls, proving remote cleanup is deferred to free-version recovery. Reverting to remote-first ordering turns this assertion red. Supporting changes: - Re-export `expire_transitioned_object` from `api::bucket::lifecycle`. - Record remote-tier mutating ops in the scanner test `MockWarmBackend`. - Update tier-ilm-debugging.md to reference the new regression test. Runs in the CI ILM Integration (serial) lane (ci.yml test-ilm-integration-serial), picked up by the existing binary(lifecycle_integration_test) filter.
