This modernizes the Windows build system by migrating from Cygwin-based dependency management to vcpkg, Microsoft's official C++ package manager. The changes eliminate external dependencies while adding comprehensive AddressSanitizer support. Key improvements: - New vcpkg-based build script (windows-release-vcpkg.ps1) - Automatic ICU dependency management via vcpkg - Enhanced CI/CD pipeline with ASAN build configuration - Simplified developer setup without Cygwin requirements - Better Visual Studio 2022 toolchain integration 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Dynamically detect LLVM/Clang ASAN library path - Set environment variables for linker to find ASAN runtime - Skip CMake compiler test which fails with ASAN flags - Add proper ASAN library path to linker flags - Works with scoop, chocolatey, or VS-installed LLVM
- Remove individual package installation (icu:x64-windows) - Use vcpkg install without arguments to install from vcpkg.json - Add proper error handling for manifest mode - Fix CI build failure
- ASAN now always builds in Release mode for best performance - Removed ASAN-Debug configuration as per request - Clang ASAN doesn't fully support debug runtime anyway - Cleaner, simpler configuration
