MAESTRO: Expand startup orphan cleanup to target mcp-server and worker-service processes

The startup cleanupOrphanedProcesses() only targeted chroma-mcp, leaving
orphaned mcp-server.cjs and worker-service.cjs processes undetected after
daemon crashes. Expanded to target all claude-mem process types with
30-minute age filtering and current PID exclusion. Closes PR #687 (which
had a spawnDaemon regression removing Windows WMIC support).
