fix(git_helper): duplicate error summary to stdout for reliable capture

execute_cm_cli() in comfy-cli captures stdout via PIPE but may not
capture stderr (depends on comfy-cli version). Add stdout echo of
error summary at clone failure and dispatch-level exception so
comfy-cli always has access to git_helper error details.

Diagnostic logs remain on stderr; stdout gets a one-line summary with
repo name, exit code, and git error message.
