No Action Required

• [VSCode] Fixed pressing Enter on the plan review card's "Send feedback and keep planning" button approving the plan instead of sending your comments back
• [VSCode] Fixed the panel showing "Something went wrong" after "Switch branch & continue" on a cloud session opened from Session history's Web tab
• [Cloud sessions] Added Claude Code cloud sessions and Remote Control permissions to Enterprise custom roles, so Owners can control access to each by role

• [Cloud sessions] Improved the session start checklist to show a cloud environment's setup script output in a scrolling box
• [Cloud sessions] Changed the cloud environment dialog to open network access, setup script and environment variables from rows instead of listing every editor at once
• [Claude Tag] Fixed Claude Tag treating ! commands such as !restart and !help as ordinary messages when sent in bold, italic or strikethrough
• [Code Review] Fixed the Code Review admin section hiding its repositories and switches after a failed refresh of the repository list
