VS Code: Agent Host Becomes the Backbone
The bulk of today's activity hardens the Agent Host platform — session migration, sandboxing, tunneling, and catalog reliability — as more surfaces, from terminal chat to Copilot CLI sessions, get routed through it. A cluster of fixes also targets sync bugs between UI and backend session state.

On the migration front, pwang347's PR 331529 and vijayupadya's PR 331606 both close gaps in moving legacy sessions onto the Agent Host — one fixing stalled customization migrations, the other making sure legacy Copilot CLI sessions migrate no matter which address a user opens. Sandy081 followed up twice, in PR…
Reliability work extended further: dileepyavan's PR 331667 reworked sandbox configuration so the runtime, not the host, owns enablement logic — a security-relevant simplification. Connor4312 contributed two related pieces: PR 331602 moves Dev Tunnels connections into the browser itself, and PR 331706 extracts shared…
