// Package extractor provides NER and relation extraction for the ingestion
// pipeline. It mirrors the Python rag/graphrag/ner package so that both
// code paths produce identical output.
//
// The C++ ThincNER engine (internal/binding/cpp/) loads spaCy model.ckpt+model.bin
// directly for NER inference. Relation extraction is pure Go regex.
//
// Usage:
//
//	ext := extractor.NewExtractor("en")
//	result, err := ext.Extract("Apple Inc. was founded by Steve Jobs.", true)
//	for _, e := range result.Entities { ... }
//	for _, r := range result.Relations { ... }
//go:build cgo_thincner
