feat: enhance Go tree-sitter parser with advanced language structures
This enhancement significantly expands the Go parser's capabilities to recognize and extract a comprehensive set of language constructs: - Added support for struct and interface definitions with proper type identification - Implemented parsing for constant declarations (both single and in blocks) - Added support for variable declarations (both single and in blocks) - Added recognition of type aliases with proper distinction from regular types - Implemented special handling for init functions - Added support for anonymous functions, including nested function literals - Improved documentation and organization of query patterns These enhancements enable more accurate code navigation, better symbol extraction, and improved code intelligence for Go codebases.
