- Optimized memory usage via string interning and extensive data sharing
- Replaced quadratic match filtering with a per-rule span map, fixing missed secrets in extremely large files and improving scan performance
- Support scanning extremely large files by chunking input into 1 GiB segments with small overlaps, avoiding vectorscan buffer limits while preserving match offsets
- Always use chunked vectorscan, eliminating the slow regex fallback for blobs over 4 GiB
- Skip Base64 scanning for blobs over 64 MB to avoid a second pass over massive files
- Increased max-file-size default to 64 MB (up from 25 MB)
