//! Execution context system for Anda agents and tools.
//!
//! Contexts carry the runtime capabilities exposed to [`anda_core`] agents and
//! tools: caller identity, request metadata, cancellation, scoped cache, object
//! storage, HTTP calls, Web3 signing, remote engine access, and per-session
//! state. Contexts are hierarchical so each agent or tool receives a scoped
//! namespace while sharing the same underlying runtime resources.
