implemented for the Test subcommand. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Output is truncated to fit the specified token limit using Hugging Face's pretrained bert-base-cased tokenizer. đŸĻ¨ Skunky: Truncation is by character, not true token boundary; see code comment for future improvement. All changes build cleanly and are isolated to the explicit requirements. --- Cargo.lock | 283 ++++++++++++++++++++++++++++++++++++++++++- Cargo.toml | 2 +- src/bin/cratedocs.rs | 23 ++++
