WebStandardStreamableHTTPServerTransport: request-related events (progress, ctx.mcpReq.notify, handler-emitted log) and the final response are now persisted to the configured eventStore whenever the request is in flight, regardless of whether a live SSE writer currently exists — mirroring the standalone-SSE path's store-first semantics. This fixes the closeSSE() poll-and-replay drop (events emitted after closeSSE() were previously silently lost) and aligns with the 2025-11-25 specification ("disconnection SHOULD NOT be interpreted as the client cancelling its request"). When an eventStore is configured, a final response sent while no per-request stream is connected is stored for replay and returns cleanly instead of throwing "No connection established"; a Last-Event-ID reconnect after the request has been retired replays the stored response and then closes the resumed stream. When no eventStore is configured, the same condition is surfaced via onerror (the response is undeliverable) and the request id is retired.
