- Add detection checks for "From Base91" (regex heuristic), consistent with existing Base64/Base85 patterns - Regenerate OperationConfig.json via script to keep metadata in sync - Add unit tests for Base91 encode/decode and a Magic chain test for Base91 Authored-by: Izai Alejandro Zalles Merino <zallesrene@gmail.com>
