… test reset (CodeRabbit on #6802) The sets are production-monotonic by design; without clearing them the cfg(test) reset left earlier tests' declared-field / installed-key state visible to later tests reusing a key name, making the disable decision order-dependent.
📝 WalkthroughWalkthroughThe class-field inline-guard test reset now clears C5a declared-field and prototype-descriptor hash sets, preventing state from persisting across tests. A changelog entry documents the reset behavior. ChangesC5a test reset cleanup

- Around line 154-159: Update the reset helper’s write-lock handling for
DECLARED_FIELD_NAME_HASHES and PROTO_DESCRIPTOR_KEY_HASHES so poisoned locks are
recovered with into_inner() or cause an explicit failure, rather than being
silently skipped. Ensure guard.take() runs for both hash sets even after a prior
test panic, preserving deterministic reset behavior.

Do not silently skip a poisoned reset lock.
If a test panics while holding either lock, write() returns Err and this helper leaves the corresponding hash set populated, reintroducing order-dependent test state. Recover the poisoned guard with into_inner() (or fail explicitly) so the reset remains deterministic.
