Refine RAI fields: real limitations with academic restraint

Soften RAI fields (dataLimitations, dataBiases, dataSocialImpact, dataUseCases)

Mark real as default config so HF viewer opens it first

Croissant: compact single-line JSON (match HF auto-gen style)

RAI: trim to concise paper-grounded prose (1-2 sentences per field)

RAI: align all phrasing strictly to paper limitations / impact / use cases (no fabricated URLs, no internal codenames)

Add NeurIPS-required RAI Croissant metadata (validated, 0 errors)

Reorder configs: all real first, all companion last

Repackage: per-split parquets + YAML configs (name=real/companion/per-tissue)

remove companion-skin.parquet (replaced by split-tagged files)

remove companion-prostate.parquet (replaced by split-tagged files)

remove companion-lung.parquet (replaced by split-tagged files)

remove real-skin.parquet (replaced by split-tagged files)

remove real-prostate.parquet (replaced by split-tagged files)

remove real-lung.parquet (replaced by split-tagged files)

Initial SenoMorph release: real (87,391) + companion (873,910)
