Subject: [PATCH 1/2] fix: rewrite github.com blob image URLs to
 raw.githubusercontent.com

- Markdown <img> tags pointing at github.com/{owner}/{repo}/blob/...
  serve the HTML web view, not the image bytes, and silently fail to
  render
- Rewrite them to raw.githubusercontent.com so embedded images in
  fetched markdown (e.g. atc-docs DevOps Playbook) load correctly

Subject: [PATCH 2/2] test(domain): drop brittle issue-count assertions

- Remove HaveCountGreaterThan(1) and NotBeEmpty() from the three
  GetIssues* tests; they coupled to live upstream issue counts and
  failed when the atc repo was down to 1 issue
- Keep success and not-null checks so the tests still verify the
  client contract without depending on data shape
