fix(ci): resolve MUSL test failures
- Use tsx instead of node for contract tests (.ts files) - Exclude linux-x64-musl-free from CI matrix (LGPL FFmpeg lacks libx264/libx265 which are GPL-licensed) - Add runtime PNG decoder detection to skip ImageDecoder tests when PNG codec is unavailable in FFmpeg build The non-free MUSL variant continues to be tested with full codec support.
