1. createWebReadableStream: Add closed flag and cancel() callback to
prevent double-close crashes when SSE streams end. This fixes the
"Controller is already closed" error that occurs when the SDK calls
response.body.cancel() on 202 responses.
2. DELETE handler: Call serverTransport.close() after terminateSession()
to properly cleanup the transport and cancel pending reconnections.
- terminateSession() notifies the server (sends DELETE request)
- close() cleans up client-side resources (abort controller, timeouts)
- Both are needed for a complete disconnect
Guard against calling controller.close() when the stream has already
been closed by an external cancellation. This can happen when the SDK
cancels the stream before the underlying Node stream emits its 'end'
event.
- Add `closed` flag to track controller state
- Guard all controller operations with closed check
- Add `cancel()` callback to handle external cancellation
- Properly destroy the Node stream on cancellation
Version 0.17.3 had TypeScript build errors that prevented successful builds. This patch release fixes those errors and bumps the version to 0.17.4.
