Broad Dockerfile matching includes valid ignore files such as Dockerfile.dockerignore, causing false parser warnings.

• Filtering: Exclude filenames ending in .dockerignore, case-insensitively, before logging or parsing. Preserve detection of Dockerfile, Dockerfile.runtime, and other supported variants.
• Regression coverage: Check silent exclusion regardless of file contents and continued detection of genuine Dockerfiles.

New Detector Checklist

Not applicable: updates an existing detector.
