Multi-stage Dockerfile (builder → export → runtime) producing a 149 MB
Ubuntu 24.04 image, verified booting end-to-end on Docker Desktop. vcpkg
fetched via shallow git fetch at the pinned baseline, release-only overlay
triplets (x64-linux, arm64-linux) to halve intermediate disk usage, and
buildtrees deleted within the RUN layer so they never land in the image or
the BuildKit cache. Binary cache mount (VCPKG_BINARY_SOURCES) makes
subsequent rebuilds restore pre-built packages instead of recompiling.
Also adds:
- docker-compose.yml for one-command local deploy
- .dockerignore (excludes clients/, build/, .git/)
- .github/workflows/build-linux.yml — CI cross-build for amd64 + arm64
with downloadable artifacts (primary path for building from Windows)
- scripts/build-linux-binaries.sh — local Docker binary extraction fallback
- deploy/linux/voicecat.service — hardened systemd unit for bare-metal
- cmake/voicecat-toolchain.cmake now auto-wires VCPKG_OVERLAY_TRIPLETS
