feat: Include receiver names in method call extraction and improve built-in filtering

Addresses method call resolution ambiguity where bare method names couldn't be distinguished from function calls. Modifies tree-sitter extraction to include receiver names (e.g., "console.log" instead of just "log") while skipping common instance references like self/this. Updates built-in filtering to be language-specific and adds Python built-in method detection based on receiver types and method names.
