V3 deterministic image-transform capability pack. By-value connector composition (service_kind=cli, no separate ingredient): one local libvips CLI ingredient exposes readiness, thumbnails, resize, PNG conversion, metadata-stripped optimized JPEG export, and WebP export via fixed catalog operations. Write-tier but approval=never: vips writes only to an engine-managed throwaway output dir and each result is captured as result.file_ref; image bytes never flow through stdout values. The output format is selected from fixed file suffixes and bounded save options, never from caller-supplied filenames or arbitrary vips flags. Requires vips on PATH (Debian/Ubuntu: apt install libvips-tools; macOS: brew install vips). Local and no-egress. Use this pack for fast local image normalization and web-ready derivatives; use specialized optimizers such as jpegoptim/oxipng when the workflow must preserve the source format exactly.
