Advertise /opt/molecule-mcp-server presence to the controlplane so the concierge fail-closed gate can refuse online-marking when the platform-agent image's MCP server binary is absent.

Adds molecule_runtime/platform_agent_identity.py with mcp_server_present().
Includes mcp_server_present in /registry/register and /registry/heartbeat payloads.
Unit tests cover the helper and payload wiring.
