Module server 

IPC accept loop.

Binds a UDS (Unix) or named pipe (Windows), accepts incoming connections, and spawns a per-connection handler task. Graceful shutdown is driven by a tokio_util::sync::CancellationToken; after cancellation, the loop drains active connections bounded by crate::config::DaemonConfig::ipc_shutdown_drain_secs.

The two Unix bind branches (RuntimeDir vs Configured) implement the Phase 8a iter-1 B2 fix: runtime-dir paths are auto-managed (parent created 0700, stale socket removed after a liveness probe). Configured paths also auto-unlink stale sockets after a liveness probe confirms no process is listening — this is required for auto-start to work after a daemon stop. Live sockets are never touched: the daemon refuses to bind if a live daemon is already listening. Non-socket files at the configured path are always rejected.
