//! xAI Computer Hub — unified runtime contract.
//!
//! Single home for the `Tool` trait, `ToolDispatch`, `ToolError`,
//! `ToolNotification`, `ToolSearchIndex`, `ToolCallContext`, `ToolStream`,
//! and the helper constructors that build well-formed streams. Adapters
//! for individual tool sources re-export from here so every tool author
//! sees the same surface.
