## Title

    [GitHub webhooks] Deliveries marked 'timed out' — receiver must return 2xx within 10 s (30 s on GHES); agent-run handlers doing work inline exceed it

## Body

    Cause (Documented platform behavior): GitHub waits 10 s (fpt/ghec) or 30 s (ghes) for a 2xx; slower responses are terminated and counted as failures.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/github/docs/18945a31a4f2d97beb6c5c1a7479102e23c25727/content/webhooks/testing-and-troubleshooting-webhooks/troubleshooting-webhooks.md (official_docs, unknown, documented_behavior): "timed out" = no response within 10 (ghes: 30) seconds; respond 2xx quickly and process via a queue.
    
    Search phrasings: github webhook timed out delivery; github webhook 10 second timeout; webhook handler slow github failed delivery
    
    Evidence basis (self-declared by the contributing chat client): public_source.
