Patch Changes

• 8fd8c8f: Fix memory leak from recursive async functions by upgrading TypeScript target to ES2017.

  The ES2016 target caused async/await to be transpiled using the __async helper which creates nested Promise chains that cannot be garbage collected when recursive async functions like requestShape() call themselves. With ES2017+, native async/await is used which doesn't have this issue.

• 5ab082b: Fix stream stopping after tab visibility changes due to stale aborted requests in PrefetchQueue.

  Root cause: When a page is hidden, the stream pauses and aborts in-flight prefetch requests. The aborted promises remained in the PrefetchQueue's internal Map. When the page became visible and the stream resumed, consume() returned the stale aborted promise, causing an AbortError to propagate to ShapeStream and stop syncing.

  The fix:

  • PrefetchQueue.consume() now checks if the request's abort signal is already aborted before returning it
  • PrefetchQueue.abort() now clears the internal map after aborting controllers
  • The fetch wrapper clears prefetchQueue after calling abort() to ensure fresh requests

  Fixes #3460
