Dockerfile.e2e

# Standalone image built straight from source, for e2e and local kind runs.
# The release image (Dockerfile) is assembled by goreleaser from a prebuilt
# dist tarball and cannot be produced by a plain `docker build`. This one can.
# The binary lands at /manager to match config/manager (command: [/manager]).
# Pin the builder to the native build platform and cross-compile via GOARCH so a
# multiarch `buildx --platform` build stays QEMU-free (Go cross-compiles fast).
