//! FFI Symbol Registration for JIT Compiler
//!
//! This module handles registration of FFI function symbols with the JIT
//! builder and declaration of their signatures in the Cranelift module.
//!
//! After the V6 cleanup (part of the v2 spec alignment), only the symbol
//! files corresponding to live `FFIFuncRefs` entries are registered. The
//! remaining Rust FFI impls that lost their symbol registration still
//! compile (some are direct-call helpers inside `ffi/math.rs` etc.) but are
//! no longer exposed to Cranelift.
