Common Indonesian religious expressions like 'Astaghfirullah', 'Astaga', 'Alhamdulillah', 'Subhanallah', dll were being flagged as vulgar_language by the LLM. Added explicit rule that these are normal religious/cultural expressions in Indonesia - not vulgar language - even in all-caps or with repeated letters.
