Convert LineLengthRule to use SwiftSyntax instead of SourceKit for
improved performance and better detection accuracy.
The SwiftSyntax implementation:
- Uses ViolationsSyntaxVisitor pattern with line-based validation
- Pre-computes ignored lines using helper visitors for efficiency
- Implements pure SwiftSyntax comment detection without SourceKit
- Correctly handles function declarations, multiline strings
- Maintains all configuration options including URL stripping
- Preserves exact line position reporting for violations
