feat: Dify-compatible retrieval API endpoint (#15704) ## Summary Dify-compatible retrieval API for external knowledge base integration. ## Changes - New handler: DifyRetrievalHandler with POST/GET /api/v1/dify/retrieval - Health check: GET /api/v1/dify/retrieval/health - Full pipeline: KB validation -> permission check -> embedding -> metadata filter -> chunk retrieval -> child chunk aggregation -> optional KG search -> response assembly - 12 tests covering all paths (success, errors, metadata filter, KG mode) - Testability: Handler dependencies defined as interfaces (KBServiceIface, ModelServiceIface, etc.) ## Files \| File \| Type \| \|------\|------\| \| internal/handler/dify_retrieval_handler.go \| New — handler + interfaces \| \| internal/handler/dify_retrieval_handler_test.go \| New — 12 tests \| \| internal/router/router.go \| Modified — route registration \| \| cmd/server_main.go \| Modified — handler wiring \| \| internal/service/kg/pipeline.go \| Modified — SetChatModel/SetEmbModel \| \| internal/service/kg/retrieval.go \| New — helper functions \| \| internal/service/kg/scoring.go \| Moved from service package \| \| internal/service/kg/search.go \| New — KG search functions \| \| internal/service/kg/types.go \| New — type definitions \| --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> 2026-06-05 21:16:25 +08:00			`package kg`
