fix: Handle JavaScript class inheritance parsing differences from TypeScript

Addresses JavaScript `class extends` producing zero inheritance edges due to tree-sitter grammar differences. JavaScript uses `class_heritage → identifier` (bare) while TypeScript wraps with `extends_clause`. Updates extractInheritance to handle bare identifier/type_identifier children when parent is class_heritage.
