Crate tau_agent_base 

Shared types, wire protocol, and utilities for the tau agent workspace.

This is the leaf crate that every other tau workspace crate depends on. Dependencies are kept minimal: serde, serde_json, thiserror, and futures (for async JSON-line I/O helpers used by the client and plugin crates).
