- Added a non-alertable zero-time semaphore acquire path for wake draining on Windows.
- Added wait-generation tracking per thread and generation-aware deferred wake entries.
- Changed wake delivery so a wake is released only if waiter generation still matches (prevents stale wake release).
- Added stale carryover filtering in wait loop for the N→N+1 wake-token race window.
What this fixes:
- Prevents obsolete wake tokens from corrupting condvar state on Windows.
- Removes the need for workaround behavior that masked unexpected wakes.
- Restores stable wait/wake behavior while staying close to original main style.
