Replaces Huly's rekoni service. Native PDF/DOCX/XLSX/PPTX/HTML/RTF/ Markdown/text extraction, IAM JWKS-verified bearer auth, 25 MB streaming upload cap, distroless image, port 4004. PNG/image OCR returns 415 in v0.1 — Tesseract bindings deferred. Module path: github.com/hanzoai/extract-svc (the canonical hanzoai/extract slot belongs to the Rust extraction crate).
