Lua language definition and registration

This module defines the Lua language support for Codanna, providing tree-sitter-based parsing and symbol extraction for Lua codebases.

AST Node Types and Symbol Mappings

The Lua parser uses tree-sitter-lua and handles the following primary node types and their corresponding symbol classifications:

Function Declarations

• Global functions (function_declaration) -> SymbolKind::Function
• Local functions (local_function_declaration) -> SymbolKind::Function (Private)
• Methods (colon syntax) -> SymbolKind::Method

Variable Declarations

• Local variables (variable_declaration) -> SymbolKind::Variable (Private)
• Global assignments (assignment_statement) -> SymbolKind::Variable

Table Constructs

• Table constructors (table_constructor) -> SymbolKind::Class (when pattern detected)
• Table fields (field) -> SymbolKind::Field

Lua-Specific Language Features

The Lua parser handles unique Lua constructs including:

• Module patterns (returning tables from files)
• Metatable-based OOP patterns
• Visibility via local keyword and underscore convention
• require() for module imports
