//! LSP capability declaration.
//!
//! This module defines what features the server advertises to clients during
//! the `initialize` handshake. Capabilities tell the client which LSP methods
//! the server supports.
//!
//! # Key Functions
//!
//! - [`create_capabilities`]: Builds the `ServerCapabilities` struct sent to clients
//!
//! # Supported Features
//!
//! - Incremental text document sync
//! - Hover, code actions, diagnostics
//! - Completions (triggered by `?` and space)
//! - Document formatting
//! - Folding ranges
//!
//! # Related Modules
//!
//! - [`super::lsp::capabilities`]: Type definitions for capability structs
//! - [`super::message_handler::lifecycle`]: Sends capabilities in `initialize` response
