"""E2E timeout tests — verify the lifecycle is resilient to hung sub-tasks.

Covers:
* Anthropic LLM hang -> panel times out -> lifecycle terminates (soft skip)
* Arc RPC commit hang -> 90s wrap fires -> pending sentinel
* Polymarket submission hang -> orchestrator catches -> dry_run fallback
* Per-judge 60s timeout -> partial collection (10/11) -> aggregator soft-skips
* Concurrent lifecycle semaphore enforces LIFECYCLE_MAX_CONCURRENCY

All tests use MockLLM (no live Anthropic). Where we simulate "hangs" we
either monkey-patch the slow callable to raise ``asyncio.TimeoutError``
immediately or compress the orchestrator's timeout knobs so the wait
returns quickly. Tests must remain fast (< 30s each).
