VS Code 1.136 adds an agent that works a pull request until it is ready to merge

The September 2 release adds Agent Merge in preview: it works through review feedback, failed checks and merge conflicts on a pull request until the branch is mergeable. The same release lets Copilot and Claude agent sessions span every folder of a multi-root workspace (experimental) and groups related chats into a session hierarchy so you can see which ones are waiting on you.

What it means The last mile of a pull request — rerunning checks, clearing conflicts, answering review notes — is the part that actually eats an afternoon.
