//! HCL-based validation for the lint command using hcl-edit
//!
//! # C4 Architecture Annotations
//!
//! This module uses hcl-edit's visitor pattern to perform comprehensive
//! validation of runbook files, replacing the Tree-sitter based approach.
//!
//! ## Features
//!
//! - **Two-phase validation**: Collection phase gathers all definitions, validation phase checks references
//! - **Circular dependency detection**: Detects cycles in variable and action dependencies
//! - **Reference validation**: Validates action outputs, signers, variables, and flow inputs
//! - **Addon integration**: Validates action parameters against addon specifications
//! - **Precise error reporting**: Span-based error locations with line/column information
