The Dockerfile only copied a fixed list of extractor dirs; new sources
were listed in shared but their manifest.ts files were absent from the
container, so discovery logged missingManifest in production.
Copy extractors/ once before npm install in builder and production, and
skip redundant per-extractor COPY lines. Add extractors/*/storage/ to
.dockerignore to avoid baking local cache into the build context.
