Add a FIFO semaphore to limit concurrent renders in the producer server, preventing Chrome CPU contention that causes beginFrame failures. - New Semaphore utility class (packages/producer/src/utils/semaphore.ts) - Both blocking render and SSE renderStream handlers acquire/release the semaphore - SSE stream sends a "queued" event when request must wait - New GET /render/queue endpoint exposes active/queued render counts - Configurable via HandlerOptions.maxConcurrentRenders or PRODUCER_MAX_CONCURRENT_RENDERS env var (default: 2) - New --max-concurrent-renders CLI flag (1-10) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
