Pull request overview
Updates VS Code’s --transient launch flow so that when the Agents sibling application is launched, it can use its own transient user-data and extensions directories under the same temporary parent folder.
Changes:
- Add new CLI args:
--agents-user-data-dirand--agents-extensions-dir. - In
--transientlaunches, createagents-data/andagents-extensions/temp subfolders and include them in the relaunch hint. - When launching the sibling Agents app, forward these directories as
--user-data-dirand--extensions-dir.
