//! ASTRegApply implementations for basic mutations

//! These implementations enable registry-based execution for mutations
//! defined in ryo-mutations.

//! # Quality Policy
//!
//! See [`super::ast_reg_apply`] for the V2 implementation quality policy.
//!
//! Key points:
//! - Each implementation must work naturally with ASTRegistry
//! - Do NOT create hacky workarounds to make tests pass
//! - If V2 cannot handle cleanly, evaluate API extensions first
