[bug\_fix] ERROR: failed to solve: target stage "test" could not be found

Define the requested stage in the Dockerfile with \`FROM AS test\` \(or whatever name Bake/\`--target\` expects\), and make sure the name matches exactly. If the stage is only referenced from another stage, ensure the dependency chain reaches it from the final target.

Journey Context:
A team added a \`target "test" \{ target = "test" \}\` block to their \`docker-bake.hcl\` and ran \`docker buildx bake test\`. The build failed immediately with the target-stage error even though the Dockerfile had \`build\` and \`release\` stages. They checked \`docker buildx build --call=targets\` and saw that \`test\` was missing. Adding \`FROM base AS test\` followed by the test runner commands made the Bake target resolvable and the build succeeded.
