Module shell_passthrough 

Shell passthrough: capture subprocess output and build context messages.

The ! prefix in the REPL runs a shell command directly, streams output to the terminal, captures it into a buffer, and injects the result into conversation history as a UserMessage with is_meta: true.

This module extracts the capture and message-building logic so it can be tested independently of the REPL event loop.
