- Merge ExcerptBlob and excerptBlobBatch into a single unified flow
that handles both single and batch requests without duplicated code
- Extract parseBatchBlobExcerptOptions to DRY the repetitive splitInts calls
- Refactor BuildBlobExcerptDiffSection to separate section building from
highlighting, enabling BuildBlobExcerptDiffSections (plural) to highlight
the file content only once for all sections instead of N times
- Add blob size limit check (MaxDisplayFileSize) before io.ReadAll to
prevent OOM on large files
