Add image-input ATS skill test run for Dani Roxberry

[droxey]

Motivation

• Provide a reproducible example of the resume-ats-pdf-optimizer workflow when only image inputs (job description screenshot + resume image) are available.
• Document constraints, risks, and a minimal edit plan so the skill can be validated and reproduced without a source PDF or raw JD text.

Description

• Add a test-run artifact at resume-ats-pdf-optimizer/test-runs/2026-04-18-dani-roxberry-pathstream-image-test.md that follows the skill template and captures Goal, Constraints, Baseline scorecard, Ranked gaps, Minimal edit plan, Chosen PDF update method, Projected post-edit score, Verification checks, and Risks.
• The file explicitly records image-quality limitations and avoids fabricating claims while preserving the resume structure and edit guardrails.
• This change is purely additive documentation to the skill and does not modify code or runtime behavior.

Testing

• Ran repository checks including git status --short and git diff resume-ats-pdf-optimizer/test-runs/2026-04-18-dani-roxberry-pathstream-image-test.md to verify the new file appears as expected and the diff is correct, and these checks succeeded.
• Inspected the file contents with nl -ba resume-ats-pdf-optimizer/test-runs/2026-04-18-dani-roxberry-pathstream-image-test.md to confirm the artifact contains the full skill-template output, and this inspection succeeded.
• Queried repository state with git rev-parse --short HEAD to capture the working-tree snapshot used for the PR, and the command completed successfully.
