Visual Studio Code 1.115 adds Agents app and major agent tools upgrades

Visual Studio Code 1.115 introduces the Agents companion app for agent-native development, enabling parallel sessions and full support for customizations. The integrated browser sees improvements such as better tool labeling, deferred results for long-running scripts, reduced tab duplication, and pinch-to-zoom support on macOS. Terminal tools now let agents interact with background terminals and receive completion notifications. These updates continue to expand automation and workflow possibilities for agent-based development inside VS Code Insiders.
