Module pool 

Process-pool IPC layer for host_mode=true execution.

This module provides the foundation types and dispatch helpers for the pool worker protocol:

• error — PoolError enum (thiserror-derived)
• protocol — PoolRequest / PoolResponse wire types (serde JSON line)
• client — PoolClient UDS client (connect + handshake + send_request)
• registry — PoolRegistry persistence + GC (registry.json)
• dispatch — worker spawn + UDS proxy orchestration (ST6)

pub use client::PoolClient;
