Adds mcpplibs.mwrap.libjpeg_turbo 3.2.1 from mcpplibs/libjpeg-turbo-m (tag mwrap-3.2.1): libjpeg-turbo's TurboJPEG API through import mcpplibs.mwrap.libjpeg_turbo;.

  • Descriptor pkgs/mwrap/libjpeg_turbo.lua: GLOBAL is the GitHub release asset, CN the GitCode mirror mcpp-res/mwrap-libjpeg-turbo, the same bytes (sha256 83cfc60f…e8ca).
  • The wrapper vendors the sources of upstream's TurboJPEG static library byte for byte and builds them without the SIMD extensions, libspng against compat.zlib, floating-point contraction off. Upstream's testorig.jpg decodes to the MD5 upstream's own regression test expects, on Linux (GCC, LLVM), macOS and Windows.
  • Consumer tests/mwrap/libjpeg-turbo-decode; installed-template check with --deploy (STATIC_NOTICES entry and a validate.yml step).
  • Plan: .agents/docs/2026-11-14-add-libjpeg-turbo-mwrap-plan.md; CHANGELOG entry under Added.

Locally: bash tests/run_members.sh libjpeg-turbo-decode ok; the installed-template check ok.

…I — JPEG compression, decompression, lossless transforms — as a C++23 module)
