hidden-char-scanner

Hidden Char Scanner is a tool designed to detect and classify hidden characters in text, including zero-width and control characters, using `Intl.Segmenter` for grapheme segmentation. Its primary use case is to identify suspicious code points that could facilitate confusables, bidirectional spoofing, or obfuscation in code reviews. Notable features include a per-grapheme risk assessment, an annotated preview interface with tooltips, and the ability to export findings as structured JSON for further analysis.
