Switch to govips for native CGO image processing
- Replace gen2brain/avif, gen2brain/webp, disintegration/imaging with govips - govips uses libvips via CGO for fast native image processing - Add libheif-dev to Dockerfile for AVIF support - Add docker-test Makefile target for running tests in Docker - Update processor.go to use vips API for decode, resize, encode - Add TestMain to initialize/shutdown vips in tests - Remove WASM-based libraries (gen2brain) in favor of native codecs Performance improvement: AVIF encoding now uses native libheif instead of WASM, significantly reducing encoding time for large images.
