[bug\_fix] Build succeeds but image is missing from \`docker images\` list

Add the \`--load\` flag to the \`docker buildx build\` command \(e.g., \`docker buildx build --load -t myimage .\`\) to export the built image to the local Docker daemon image store.

Journey Context:
A developer switches from standard \`docker build\` to \`docker buildx build\` to take advantage of BuildKit features. The build logs show successful completion, but when they try to run the container with \`docker run myimage\`, they get an 'invalid reference format' or 'image not found' error. They frantically check the Dockerfile for typos and rebuild multiple times. The rabbit-hole leads them to inspect the buildx drivers. They realize they are using the default \`docker-container\` driver \(which runs the build inside a separate container\). Unlike the default \`docker\` driver, the \`docker-container\` driver builds the image inside its own isolated container space and does not automatically push it back to the host's local Docker daemon. Adding \`--load\` tells BuildKit to export the image from the builder container into the local daemon, making it available for \`docker run\`.

environment: Docker CLI with Buildx plugin, default or custom buildx builder using the \`docker-container\` driver. · tags: buildx buildkit load driver image-missing · source: swarm · provenance: https://docs.docker.com/build/building/drivers/docker-container/\#build-and-load-results
