- Bump base image in docker/Dockerfile.app from golang:1.24 to golang:1.26
to match `go 1.26` declared in go.mod (fixes CI build failure on
`go mod download`).
- Drop unused docreader components and their dependencies:
- Remove `docreader/ocr/` package (paddle/vlm/dummy backends are
unreferenced by the main flow; OCR/VLM is handled by the Go App).
- Remove `docreader/parser/storage.py` (dead code; image persistence
happens in the Go App via inline ImageRef bytes).
- Remove `docreader/scripts/download_deps.py` (PaddleOCR pre-download).
- Drop deps: paddleocr, paddlepaddle, openai, ollama, minio,
cos-python-sdk-v5, oss2, asyncio, pypdf2, markdown, mistletoe,
goose3, markdownify, pdfplumber, antiword, urllib3.
- Re-lock uv.lock: 145 -> 79 packages.
- Update docreader/README.md to reflect that OCR/VLM/storage are no
longer configured at the docreader level.
