Subject: [PATCH]  fix: disable reranker by default since it is not yet
 implemented

The reranker feature was documented and configured as enabled by default but the actual implementation in search.rs explicitly disables it with a comment stating it requires a separate backend. This caused users to download a ~400MB reranker model that was never used.

Changes:

- Set use_reranker default to false in config.rs

- Only download reranker model when explicitly requested with --reranker-only flag

- Update README.md to clarify reranker status as not yet implemented

 -m Fixes PlatformNetwork/bounty-challenge#24

 Models are downloaded to `~/.cache/huggingface/` and cached automatically.
