//! Built-in SPARQL Functions — Facade
//!
//! This module re-exports all SPARQL 1.1 built-in functions and provides the
//! central registration entry point. Implementation details live in:
//!
//! - [`crate::builtin_string`]   — string, type-check, logical, and regex functions
//! - [`crate::builtin_numeric`]  — numeric/math functions
//! - [`crate::builtin_datetime`] — date/time, hash, and aggregate functions
