ci/cd: build vcpkg ports release-only via an overlay triplet

vcpkg builds every port twice (release + debug) in manifest mode and the VCPKG_BUILD_TYPE environment variable is ignored there; pin the build type in overlay triplets instead (tooling/vcpkg-triplets/release, one per supported triplet). The release configuration is what both workflows consume: FFMPEG_DIR drives the release layout (lib/pkgconfig) and the C ABI is identical for the debug binary CI tests. Verified locally in debian:12: a release-only overlay builds zlib/libpng/openssl/pkgconf/ libsndfile with zero debug trees. Debug-only is not an option: ports like zlib patch files in the release layout and fail when only the debug configuration is built.

+# vcpkg overlay triplets
+
+Small overlays over vcpkg's builtin triplets, passed to `vcpkg install`
+with `--overlay-triplets <dir>` (both workflows, see
+`.github/workflows/ci.yml` and `.github/workflows/cd.yml`).
+
+`release/` pins every supported triplet to the release configuration
+(`set(VCPKG_BUILD_TYPE release)`): vcpkg otherwise builds every port
+twice — release and debug — which doubles the FFmpeg/port build time in
+CI and CD. Our build scripts only ever consume the release layout
+(`FFMPEG_DIR=<prefix>` with `<prefix>/lib/pkgconfig`, plus the linker
+paths those `.pc` files carry), so the debug half was pure waste; the C
+libraries' ABI is identical for the debug cargo binary CI tests.
+
+Notes:
+
+- The non-build-type settings mirror vcpkg's builtin triplets
+  (`scripts/triplets/`) so the overlay stays a drop-in replacement; a
+  vcpkg upgrade that changes a builtin triplet should be mirrored here.
+- `VCPKG_BUILD_TYPE` must be set in the triplet: the environment
+  variable of the same name is ignored in manifest mode.
+- Do not try `debug` here: several ports (e.g. zlib) patch files in the
+  release layout and fail when only the debug configuration is built.
