Initial release: Swift Result Builders for collections and strings

Implements comprehensive result builders for Swift including:
- ArrayBuilder: Type-safe array construction with control flow support
- SetBuilder: Set construction with duplicate handling and array support
- StringBuilder: String building with newline joining
- MarkdownBuilder: Markdown document construction with formatting options

Features:
- Full result builder protocol support (conditionals, loops, optionals)
- Performance optimized implementations
- Comprehensive test coverage
- Swift Package Manager integration with individual library products
- Clean API with proper disambiguation
- Minimal dependencies (no Foundation imports)

Package provides both unified "Builders" library and individual component libraries for selective importing.

This provides a foundation for declarative collection and string building in Swift applications.
