Fixes#61
Thread AbortSignal from the top-level API through RunContext to
executeQueue(), enabling graceful cancellation in Express, Next.js,
serverless, and CLI scenarios.
Changes:
- Added optional to RunContext interface
- now accepts
- now accepts
- executeQueue() checks signal.aborted before each dispatch round
and skips remaining tasks when cancelled
- Signal is forwarded to coordinator's run() and per-task pool.run()
so in-flight LLM calls are also cancelled
- Full backward compatibility: both methods work without options
The abort infrastructure already existed at lower layers
(AgentRunner, Agent, AgentPool) — this commit bridges the last gap
at the orchestrator level.
