Macro for safe debug logging with automatic string truncation

Use this instead of log::debug!() when logging string slices that might contain multi-byte UTF-8 characters. It automatically truncates safely.

Examples

use marco_core::safe_debug;

let input = "Text with emoji 😀 and em dash —";
safe_debug!("Parsing paragraph from: {:?}", input, 40);
safe_debug!("Short preview: {:?}", input, 20);
