Make codegraph_explore language-agnostic

- Pattern generation now uses multiple naming conventions:
  PascalCase, snake_case, and camelCase
- Common suffixes/prefixes work across languages (Service,
  Handler, Controller, handle_, create_, etc.)
- Removed JS/React-specific patterns like useBundle, SwapDialog
- Bump version to 0.1.6
