// DefaultLanguageResolver maps the language strings stored on
// KindFile nodes to their tree-sitter binding. The mapping covers
// every language the bundled detectors reference plus a handful of
// extras for raw-pattern queries. Languages that fall outside this
// list return nil — the engine then skips the matching targets
// (ast-grep behaves identically when its grammar isn't available).
//
// To extend: add the import + entry here. The detector definitions
// reference languages by string, not by binding pointer, so adding a
// language here doesn't require touching detectors.go.
