completion.rs

//! Context-aware completion for Lex documents.
//!
//! Provides intelligent completion suggestions based on cursor position:
//!
//! - **Reference context**: Inside `[...]` brackets, offers annotation labels,
//!   definition subjects, session identifiers, and file paths found in the document.
//!
//! - **Verbatim label context**: At a verbatim block's closing label, offers
//!   standard labels (`doc.image`, `doc.code`, etc.) and common programming languages.
//!
//! - **Verbatim src context**: Inside a `src=` parameter, offers file paths
//!   referenced elsewhere in the document.
//!
//! The completion provider is document-scoped: it only suggests items that exist
//! in the current document. For cross-document completion (e.g., bibliography
//! entries), the LSP layer would need to aggregate from multiple sources.
