refactor(scanner): migrate to Swift Regex and remove NSString bridges#288
Merged
Conversation
Replace `NSRegularExpression` with Swift `Regex` literals and `Regex(pattern)` across the scanner pipeline. Fall back to `NSRegularExpression` in `BinaryStringScanner` for patterns using lookbehind (unsupported by Swift Regex). Replace `(string as NSString).lastPathComponent` casts with `URL(fileURLWithPath:)` in `IPSWExtractor`.
