native-dependency-update

Update native dependencies (libpng, libexpat, zlib, libwebp, harfbuzz, freetype, libjpeg-turbo, etc.) in SkiaSharp's Skia fork. Handles security CVE fixes, bug fixes, and version bumps. Use when user asks to: - Bump/update a native dependency (libpng, zlib, expat, webp, etc.) - Fix a CVE or security vulnerability in a native library - Update Skia's DEPS file - Check what version of a dependency is currently used - Analyze breaking changes between dependency versions Triggers: "bump libpng", "update zlib", "fix CVE in expat", "update native deps", "what version of libpng", "check for breaking changes". For security audits (finding CVEs, checking PR coverage), use the `security-audit` skill instead.
