atomr-agents-state 0.2.1

//! Channelled state, reducers, and per-super-step checkpointing.
//!
//! Implements LangGraph's StateGraph state model in atomr-agents
//! idioms. A `StateSchema` declares a channel per state key; each
//! channel carries a reducer that merges the current value with
//! incoming writes. `RunState` holds the values and exposes
//! `merge_writes` for batch application after each super-step. A
//! pluggable `Checkpointer` persists snapshots so workflows can
//! resume, replay, and fork.
