Crate turul_a2a_aws_lambda 

AWS Lambda adapter for turul-a2a.

Thin wrapper: converts Lambda events to axum requests, delegates to the same Router, converts responses back. Per ADR-008/ADR-009:

• Authorizer context mapped via synthetic headers with anti-spoofing
• Streaming supported via durable event store (D3)
• SSE responses are buffered: task executes, events are collected, returned as one response
• POST /message:stream executes the task within the Lambda invocation and returns all events
• GET /tasks/{id}:subscribe replays stored events (works best for terminal tasks)

Lambda streaming is request-scoped (not persistent SSE connections). The durable event store ensures events survive across invocations. Clients reconnect with Last-Event-ID for continuation.
