fix: synchronous endpoint + Cloud Run scaling (fixes prod timeout)#282
Conversation
The fire-and-forget + semaphore design caused all jobs to queue on one instance. Cloud Run couldn't see background threads as "busy" so it never scaled to new instances. Fix: make endpoint synchronous (await executor) with concurrency=1. Cloud Run sees each request as active during processing and scales to new GPU instances for concurrent jobs — matching Modal's .spawn(). Increase client POST timeout to 1800s to match.

Hotfix for prod job timeout. Remove GPU semaphore, make endpoint synchronous, increase POST timeout to 1800s.
