theway-daemon 0.1.25

//! Daemon-side composition of [`ExternalProtocolOps`]: one object that owns
//! command dispatch, session lifecycle, observability, graph, tool, storage,
//! and settings operations. Protocol servers hold this single object and only
//! adapt parameters/errors to gRPC, JSON-RPC, or MCP.
