Command execution now attaches a commandRun marker to transcript messages

What

When a command is run, whether immediately in the local session or via a bridge, the resulting transcript message now carries a commandRun field alongside its existing text and error content.

Why

This appears to record which command produced a given transcript entry, likely for tracking or displaying command-run history more precisely.
