hirn-exec 0.1.0

//! `hirn-exec` — DataFusion physical operators, scoring UDFs, and optimizer rules.
//!
//! This crate provides the execution layer for hirn's cognitive memory engine,
//! built on top of Apache DataFusion. Every cognitive operation (activation,
//! scoring, budgeting, causal reasoning) is expressed as a composable DataFusion
//! physical operator over Arrow columnar batches.
//!
//! # Modules
//!
//! - [`operators`] — Physical `ExecutionPlan` implementations (19 operators)
//! - [`udfs`] — Scalar UDF implementations (8 UDFs)
//! - [`rules`] — Physical optimizer rule implementations (5 rules)
//! - [`extensions`] — `HirnSessionExt` for runtime state injection
