Boshen 621808eb31 perf(diagnostics): measure graphemes lazily (#25723 )

Lazily measure non-ASCII graphemes instead of allocating an eager
boundary table.

Criterion single_unicode_tab: 1.1575 µs → 596.36 ns (-48.6%). ASCII
cases remain neutral or better. Kibana output is unchanged; end-to-end
performance is neutral without type-aware linting.

AI-assisted.
