Dockerfile.native

# GraalVM native-image build of qtsurfer-mcp. Produces a single ELF binary
# packaged in a distroless runtime image.
#
# Target platform: Linux x86_64 (build on claude-builds LXC or any GraalVM host).
#   docker build --platform linux/amd64 -f Dockerfile.native \
#     -t qtsurfer/mcp-native:0.2.0 .
#
# To extract the binary without running the image:
#   docker create --name mcp-native qtsurfer/mcp-native:0.2.0
#   docker cp mcp-native:/app/qtsurfer-mcp ./qtsurfer-mcp
#   docker rm mcp-native

# --- Stage 1: build the native binary inside the GraalVM CE 25 image. ---
