aam-rs 2.0.0

#![cfg(any())]

//! Comprehensive error handling and recovery tests for AAML (500+ test cases).
//!
//! Tests all error cases and validation paths covering:
//! - Parse errors (assignments, directives)
//! - Type validation errors (primitives, math, time, physics)
//! - Schema validation errors
//! - Directive errors (@import, @derive, @schema, @type)
//! - Custom error diagnostics
