8 acceptance tests with real LegCo PDFs (all @pytest.mark.acceptance + @slow).
Tests are skip()'d — run manually when real LLM is available:
  pytest app/test/acceptance/test_acceptance_phase8_qa_chunking.py -v -m acceptance

Sub-Phase 8.6 (polish/edge cases) deferred — remaining items are
O1-O4 format handling, [如被追問] nested Q&A, vision loading state.
Core algorithm (8.1-8.4) is test-passing and production-ready.

+Prerequisites:
+- ChromaDB running (local)
+- .env configured with valid LLM_BASE_URL, LLM_API_KEY, LLM_MODEL_NAME
+- Test PDFs available in ../../test materials/LTT/
+
+These tests require real LLM calls and actual LegCo PDFs.
