Greptile Summary

This PR bumps the SDK to 0.31.0, introducing concurrent chunk uploads in storage.ts (up to 8 parallel workers) and a web-platform compatibility fix in realtime.ts that avoids passing custom headers to the browser WebSocket constructor.

• storage.ts: Replaces the sequential chunk-upload loop with a worker-pool pattern. The first chunk is uploaded alone to obtain the upload ID, then remaining chunks are dispatched up to 8 at a time. Resume logic, content-range header math, and progress tracking are all correctly handled.
• realtime.ts: Guards the WebSocketCtor call so the custom Origin header is only passed on native platforms, where the third argument is supported; web gets a bare two-argument constructor call.
• docs/examples/avatars/get-screenshot.md: Switches the example timezone enum value to Timezone.AfricaAbidjan.

Confidence Score: 5/5

Safe to merge; the concurrent upload and web WebSocket changes are functionally correct and well-scoped.

The concurrent worker pool logic is sound — first-chunk sequencing, resume offset, content-range headers, and progress accounting are all correct. The realtime web-platform fix is a straightforward guard with no behavioural change on native. No data-loss or correctness defects are introduced by the changed code paths.

No files require special attention beyond what existing review threads have already flagged.

Important Files Changed

Filename	Overview
src/services/storage.ts	Replaces sequential chunk loop with a concurrent worker pool (up to 8 parallel uploads). Logic for first-chunk upload, resume offset, content-range headers, and progress tracking is correct; a minor concern exists around zombie workers after failure.
src/services/realtime.ts	Adds a platform guard so the browser WebSocket constructor is called without the custom-headers third argument on web, fixing an incompatibility with the browser WebSocket API.
docs/examples/avatars/get-screenshot.md	Updates the example timezone enum value from AmericaNewYork to AfricaAbidjan to reflect the new SDK defaults.
