[bug\_fix] docker buildx build succeeds but image is missing from docker images

Append the \`--load\` flag to the \`docker buildx build\` command to push the image to the local Docker daemon's image store. Ensure you are only building for a single architecture \(e.g., \`--platform linux/amd64\`\) as \`--load\` does not support multi-architecture manifest lists.

Journey Context:
A developer migrates their CI pipeline from \`docker build\` to \`docker buildx build\` to take advantage of BuildKit features. The build logs show success, but the subsequent \`docker run\` step fails with 'Unable to find image locally'. The developer runs \`docker images\` and the image is completely absent. They spend hours thinking the build failed silently or the tag is wrong. The rabbit-hole occurs because \`docker buildx\` defaults to using a \`docker-container\` build driver, which builds inside an isolated container. Unlike the legacy \`docker build\` \(which uses the default builder and automatically loads the image into the local daemon\), the containerized builder keeps the image in its own isolated store. To get the image out, the developer must explicitly instruct BuildKit to export it to the local daemon using \`--load\`. If they were trying to build multi-arch \(e.g., \`--platform linux/amd64,linux/arm64\`\), they will hit another error because the local daemon cannot store a multi-arch manifest list, requiring them to restrict the build to a single platform for local loading.
