//! GraphQL June 2018 specification validation rules.
//!
//! Implements all 25 validation rules from the GraphQL June 2018 specification,
//! covering executable document validation, fragment rules, variable rules,
//! directive rules, argument rules, type coercion, and field-merge conflict detection.
//!
//! The implementation is split across sibling modules:
//! - `operations`: operation/type/variable rules + shared helpers
//! - `fragments`: fragment rules
//! - `directives`: directive/argument/value/field-merge rules
//! - `tests`: integration tests (cfg(test) only)
