Implementation of the upgrade_mutex itself plus mh::upgrade_lock and mh::upgrade_to_unique_lock. Tests and local build-matrix verification follow in subsequent commits. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JjaYdGSpbpKq2BuFUF9Sce
10 test cases: single-thread state machine, try_lock matrix, the writer-priority gate (pending upgrade blocks new shared acquires), upgrade-slot exclusivity and serialization, downgrades, std/mh RAII wrappers, upgrade_to_unique_lock round trip, and a bounded multi-word invariant stress test intended for TSan runs.
