Pull request overview

Adds CI automation to build a PR-scoped “dev” Docker image for mongot from this repository’s source, publish it as a GitHub Actions artifact, optionally push it to Docker Hub when credentials are available, and clean up the per-PR Docker Hub tag when the PR closes.

Changes:

• Add a dev Docker image definition (Dockerfile + entrypoint) for running mongot from a bundled build artifact.
• Add a PR workflow that builds //deploy:mongot-community, assembles a Docker build context, builds the image, and uploads it as an artifact (optionally pushes to Docker Hub).
• Add a cleanup workflow that deletes the pr-<number> Docker Hub tag when the PR is closed.

• The conditional only checks for DOCKERHUB_TOKEN, but this step assumes DOCKERHUB_USERNAME was configured (and the login step ran). Guard on both to avoid attempting a push when credentials are incomplete.

      - name: Push image to perconalab
        if: env.DOCKERHUB_TOKEN != ''
        run: |

• This workflow doesn’t declare permissions, so it will inherit the repo’s default GITHUB_TOKEN permissions (often broader than needed). Since the job only talks to Docker Hub, explicitly set minimal permissions (e.g. none).

• Comment typo: “execed” should be spelled “exec'ed” (or similar).

# config supplied via CMD. Any other command (e.g. `sh`) is execed as-is
