jif c983a53f20 Add character n-gram skill selection (#33613) ...

## What changed

- Add a character n-gram selector that scores matches across skill names, short descriptions, and descriptions using field weights and inverse document frequency.
- Include the selector in the shadow selection experiment alongside the existing lexical selectors.
- Bound query, document, candidate, and result processing, and report query or candidate truncation through the existing selection metadata.

## Testing

Add unit coverage for related word forms, typos, CJK text without word boundaries, and bounded inputs.
