Pull request overview
This PR adds support for customizing how terminal commands are displayed in the chat UI without changing the actual command that gets executed. This is particularly useful for background agents that may want to show extracted code (e.g., Python code from a python -c "..." command) with appropriate syntax highlighting instead of the full shell command.
Changes:
- Added
presentationOverridesproperty to theChatTerminalToolInvocationDataAPI interface to allow overriding command display and syntax highlighting language - Updated the type converter to properly transform the extension API data to internal format including the new presentation overrides
- Modified the terminal tool progress part to use the presentation overrides when displaying commands in collapsible wrappers for the thinking container
