1//! # LanguageFeatureProvider (Environment)
2//!
3//! Provides language feature intelligence through extension-hosted LSP
4//! providers. Manages provider registration, lookup, and invocation for hover,
5//! completion, definition, references, formatting, code actions, and more.
6//!
7//! ## Implementation Strategy
8//!
9//! The trait implementation is split across multiple helper modules:
10//! - `Registration`: RegisterProvider, UnregisterProvider
11//! - `ProviderLookup`: GetMatchingProvider (private helper)
12//! - `FeatureMethods`: All LSP feature methods (Hover, Completion, etc.)
13//!
14//! The single `impl LanguageFeatureProviderRegistry for MountainEnvironment`
15//! block in this file delegates to those helper functions. This satisfies
16//! Rust's orphan rules while keeping code organized and atomic.
