claw-code/rust/crates/runtime/src/lib.rs

//! Core runtime primitives for the `claw` CLI and supporting crates.
//!
//! This crate owns session persistence, permission evaluation, prompt assembly,
//! MCP plumbing, tool-facing file operations, and the core conversation loop
//! that drives interactive and one-shot turns.
