* [Benchmark] Add MMRarebench dataset support

- Add 4-track medical rare disease benchmark
- Support HuggingFace datasets for automatic download
- Support base64-encoded images in TSV files

* [Benchmark] Fix MMRarebench lint issues

* [Benchmark] Fix MMRarebench lint: remove unused import, fix isort, add explicit smp imports

- Remove unused DEBUG_MESSAGE import (F401)
- Add noqa F401,F403 to star import from ..smp
- Add explicit imports for load, dump, read_ok, np to resolve F405
- Fix isort ordering in mmrarebench.py and __init__.py

* [Benchmark] Fix MMRarebench lint issues in mmrarebench.py

* [Benchmark] Fix isort: remove extra blank line in mmrarebench.py

* [Benchmark] Fix isort: move mmrarebench import to correct alphabetical position in __init__.py

* [Benchmark] Sync lint config from main and fix MMRarebench imports

- Sync .pre-commit-config.yaml: add isort hook, upgrade flake8 to 7.1.2
