docs(mirror): prep for github.com/recklessop/ai-workflow-course public mirror

- README: drop blog/ and handoff.md from the layout (won't be on the mirror),
  repoint the wiki URL to the GitHub wiki, refresh the Status line with the
  skip-friendly lab note.
- Module 1 download URL: point at the github.com/recklessop mirror so the
  public copy's "Get the course materials" step resolves.
- the-workflow-syllabus.md: reflect the AI-drives-git reframe (M1-3 by hand;
  M4 pivot; calculator analogy; learner directs+verifies, doesn't type git),
  Claude Code as the concrete worked example (model-agnostic in principle),
  Module 6 rescoped to "Branches: Sandboxes for AI Experiments" (M3 first-teaches
  branches; M6 doesn't re-teach), lesson=theory rule, the skip-friendly lab
  format, and no-slop voice. All 27 modules + capstone preserved; nothing
  reordered. Em-dash count: 0.
- .github/workflows/ci.yml: fix the hardcoded owner to `recklessop`.
