fix(external-workspace): pin molecule-ai-workspace-runtime>=0.1.999 in OpenClaw snippet

Ensures the molecule-mcp console script (heartbeat + register-on-startup) is present on install. Older versions only ship a2a_mcp_server which does not heartbeat, causing workspaces to go OFFLINE within 60s.

Closes openclaw keepalive regression.
