Copernicus Product Discovery

Purpose

Find Copernicus products that best match a user's data need. Use the repository's local metadata under outputs/ as the source of truth, not memory.

The default workflow is retrieve-then-rerank:

1. Build compact product documents from the metadata tables.
2. Retrieve a candidate set with fast lexical matching.
3. Rerank candidates with cross-encoder/ettin-reranker-17m-v1.
4. Return concise recommendations with service, title, id/code, why it fits, relevant variables/coverage/timing, and URL when available.
