feat: real PDF pipeline test — end-to-end knowledge extraction working
Add full pipeline test that generates a real PDF, processes it through the entire pipeline, and verifies knowledge lands in FalkorDB: - Create test PDF generator using pdf-lib (2-page doc about Acme Corp) - Add testFullPipeline() to integration tests with store verification - Fix FalkorDB client connect() — createClient returns unconnected client in both TriplesStore and TriplesQuery classes Results: PDF decoded (2 pages) → chunked (2 chunks) → extracted (4 relationships) → 16 triples stored in FalkorDB including: alice-johnson → is-a-senior-engineer → acme-corporation cloudsync → uses-aws-for-hosting → amazon-web-services provenance: pages → prov:wasDerivedFrom → source document Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
