AI Summary

Resolves hanging issues and timeouts in interactive commands (`snapshot -C`, `screenshot --annotate`) when connected over WebSocket Secure connections.

Key Highlights

Batches CDP calls for cursor-interactive mode to prevent timeouts on high-latency WSS
Batches element queries for screenshot annotation to reduce completion time
Fixes hanging behavior over WSS connections

Full Release Notes

### Patch Changes

-   5fa2396: ### Bug Fixes

    -   Fixed **`snapshot -C`** and **`screenshot --annotate`** hanging when connected over WSS (WebSocket Secure) due to sequential CDP round-trips per interactive element (#842)

    ### Performance

    -   **`snapshot -C` (cursor-interactive mode)** now batches CDP calls instead of issuing N×2 sequential round-trips per cursor-interactive element, preventing timeouts on high-latency WSS connections (#842)
    -   **`screenshot --annotate`** now batches element queries, reducing completion time from potentially 20–40s (e.g. 50+ buttons over WSS) to within expected bounds (#842)
