🔧 Fixes

CRITICAL: Fixed PDFium bundling in wheels by correcting feature flag in conditional compilation
- Root cause: Code was checking for legacy pdf-bundled feature in #[cfg()] but feature was renamed to bundled-pdfium
- Feature aliases don't apply to Rust conditional compilation - only to dependency resolution
- Result: Bundled PDFium module was never compiled when bundled-pdfium was enabled
- Fixed all #[cfg(feature = "pdf-bundled")] to #[cfg(feature = "bundled-pdfium")] in pdf module
- Verified: Python wheels now successfully extract and initialize PDFium at runtime

Fixed MSBuild target to prevent overwriting CI-downloaded native assets
- Added conditional logic to detect if runtimes directory already populated with cross-platform files
- Prevents build step from creating empty platform directories that overwrite CI artifacts
- Supports all platforms: Windows (x64/arm64), macOS (arm64/x64), Linux (x64/arm64)

Added unsafe keyword to extern blocks in Ruby bindings
- Required by Rust 2024 edition for extern "C" declarations

Fixed unused import warning in pdf extractor
- Added #[cfg(feature = "tokio-runtime")] to conditional import of std::path::Path

Fixed ONNX Runtime package installation
- Corrected Debian Trixie package name from libonnxruntime to libonnxruntime1.21
- Applied to both Dockerfile.core and Dockerfile.full
- Verified: Both Docker images build successfully and PDF extraction works with bundled PDFium

Added bundled-pdfium feature to kreuzberg-cli dependency
- Ensures CLI binary includes embedded PDFium without requiring system installation

Fixed path traversal calculation in test script
- Changed from 2 levels (/../..) to 3 levels (/../../..)

Disabled on Windows CI to prevent hanging
- soffice binary lookup hangs on Windows runners
- Added #[cfg(not(target_os = "windows"))] to 12 LibreOffice test cases
