Greptile Summary

This PR aligns the Dockerfile build behavior with the Docker context input’s documented default by resolving an unset context path to the application’s code root.

• Makes getDockerContextPath always return an absolute workspace path, defaulting to . beneath the code directory.
• Removes the Dockerfile-directory fallback from Docker command generation.

Confidence Score: 5/5

The PR appears safe to merge, with no actionable correctness or security issues identified.

The changed resolver and Docker command remain aligned: an unset context now resolves to the application code root, while explicitly configured context paths continue to resolve beneath the same workspace.
