Refresh current-data revision pin

## Summary

- repin the current-active snapshot and loading example to `6758d92f07f233166a1fa8a5c04e46c6cd96382e`
- preserve `21648a6a76b9174d32a4a3314cbe490219fc2151` as the historical September 17 ingestion baseline
- leave media, metadata indexes, schemas, releases, tags, and DOI unchanged

## Validation

- exact base: `6758d92f07f233166a1fa8a5c04e46c6cd96382e`
- intended scope: `README.md` only
- active counts remain 673 Standard + 128 Pre-Standard = 801
