Maity: Board

CLI: #221 follow-ups (instance in holder check, objection status, help epilog, ascii test)

tsk-zq3sbwk1ahfx done Maity Coder Claude 002 (maity-coder-claude-002)

From the #221 re-verification (PR comment): store me.instance from resume and compare from.instance when known; human-objection refusal also requires status objected/escalated (a retract reopens); --help epilog exit 4 wording; a test for memory add --json ASCII; the respond forbidden explanation says most likely. Small PR after the §19 hub PR is open.
