VS Code 1.129 change AI Agent Sharing Across Multiple Windows

VS Code 1.129 just untethered AI agents from individual windows. That's a small line in the release notes and a big shift in how an agent is supposed to behave in an editor — and worth understanding for anyone who's spent the last year chasing tabs back to the window they started their agent in.

Until now, an agent session in VS Code was welded to the window you launched it in. Open a second window on the same repo to check a file? That second window knew nothing about the agent running next door. Close the original window, lose your place, or scroll back through chat history to recover context.
