1//! Provider enum and core definitions shared across VT Code crates.
2//!
3//! This module provides the [`Provider`] enum and its pure methods. Methods
4//! that depend on model catalogs or vtcode-config internals
5//! (`supports_reasoning_effort`, `supports_service_tier`) remain in
6//! `vtcode-config` as extension methods.
