1//! Core runtime engine for Common Agent Runtime.
2//!
3//! The runtime loop:
4//! 1. Receive a proposal (batch of actions from a model)
5//! 2. Build a DAG from state_dependencies
6//! 3. Execute each level (concurrent if no ABORT actions, sequential otherwise)
7//! 4. Validate, execute with idempotency + timeout + retry, commit
8//! 5. On abort: rollback state to pre-proposal snapshot
