agent: launcher probes harnessd liveness with a real request

Browse Source 
A stale socket file survived a container idle window while the daemon
died; the [ -S ] check skipped the restart and the nested agent's MCP
server crashed at connect. The agent refused cleanly (no ledger row, no
fabrication). Liveness now means answering read_playbook, not existing.
