Panic with max_extracted_len

[CodedNil]

❯ 21:04:43 [server] thread 'tokio-rt-worker' (104310) panicked at /home/dan/.cargo/registry/src/index.crates

This code can split within a character boundary which panics

      // Apply maximum length limit
      if result.content_text.len() > options.max_extracted_len {
          result.content_text.truncate(options.max_extracted_len);
          result.warnings.push(format!(
              "Content truncated to max length: {}",
              options.max_extracted_len
          ));
      }

This can be fixed with the rust 1.91 feature floor_char_boundary or other methods if you want to stick with older rustc.

result.content_text.truncate(result.content_text.floor_char_boundary(options.max_extracted_len));
