fix(agent-cli): httpRequest rejects when the connection drops mid-body (#615 merge-time fix)

The response listened for 'data' and 'end' only. A socket closed after the
headers emits 'error' on the response and never 'end', so the promise never
settled. A one-shot `codeman agent` just exits, but the long-lived
`codeman mcp` left that tool call unanswered forever.
