Teknium a90d5369f7 feat(gateway): dump wedged worker stacks when the turn reaper fires
When the inactivity reaper interrupts a timed-out turn, the interrupt
frees the blocked frame — destroying the only evidence of where the
turn was wedged. The Aug 2026 zombie-turn incident (WhatsApp session,
Relay-corrupted scope stack) wedged every turn for exactly the 1800s
timeout somewhere between 'Turn ended' and run_sync returning, and the
wedge point was unprovable post-mortem.

The reaper now logs the stack of every thread with turn-machinery
frames BEFORE interrupting, so the next occurrence names the exact
blocked line. Best-effort, bounded (8 threads, 25 frames), pure
in-process, never raises into the reaper.
