jif 5e96aabd68 Avoid full-string scans in token-budget truncation (#49712) ...

## Why

Token-budget truncation uses byte counts to estimate tokens, but previously scanned the entire string to count characters, including the discarded middle.

## What changed

Use UTF-8 boundary lookups to select the retained prefix and suffix for token-budget truncation. Skip character counting for a zero-token budget and defer it to paths that need character counts.

## Testing

Add regression coverage for multibyte characters crossing both retained boundaries, checking the truncated output and original token estimate.
