/**
 * AgentWorker — Standalone agent process that registers with the daemon,
 * connects via WebSocket, sends heartbeats, and executes tasks.
 *
 * Modes:
 *   - In-process: Spawned by `memi agent spawn <role>`, uses engine directly
 *   - Remote: Connects to a running daemon via WebSocket on ports 9223-9232
 *
 * Usage:
 *   Spawned by `memi agent spawn <role>` or run directly.
 *   Connects to the bridge, registers itself, sends heartbeats,
 *   and claims tasks matching its role.
