Test-only. Bounds the Python lock holder's HELD read so a lock leaked on refusal fails by name instead of hanging, and pins the late check and release in Rust try_compare_exchange_snapshot (a cfg(test) hook between the pre-lock look and the try-lock).

Follow-up: variants:follow_up:link-late-check-lows. Report: variants:cut_report:cut-cut-link-late-check-lows.h1.

Details

The Python holder's HELD read is bounded, so a lock leaked on refusal fails the
subtest naming the leak instead of hanging CI. A test-only hook runs a closure
between try_with_exclusive_lock's pre-lock look and its try-lock, so a test puts
the link there and checks the refusal, the untouched target and the freed lock.
