OxiPNG Pack
V3 deterministic PNG optimization capability pack. By-value connector composition (service_kind=cli, no separate ingredient): the local oxipng CLI writes an optimized PNG to a fixed engine-owned output path via image.optimize_png. This pack deliberately avoids in-place mutation by using oxipng's --out option. Write-tier but approval=never: oxipng writes only under {out_dir} and the optimized PNG is captured as result.file_ref. Requires oxipng on PATH (Alpine: apk add oxipng; Rust environments: cargo install oxipng). Local and no-egress.
