fix: pedagogical review - add expected output, CLAUDE.md, fix consistency

Address findings from pedagogical review simulating a non-expert user:

- Add CLAUDE.md to project root (was referenced but missing)
- Fix README score from 12/9/1 to 13/8/1 (match feature-map.md)
- Add Expected Output sections to examples 01, 02, 05, 09, 10
- Create pipeline-output/ and briefings/ directories
- Add example ordering guidance in README
- Add plan requirements for examples 11/13 in prerequisites
- Add skill frontmatter explanation in GETTING-STARTED.md
- Explain Cowork/Dispatch with links in cowork-integration
- Expand .gitignore with node_modules and generated output files
- Add model override hints in agent frontmatter comments

+## Expected Output
+
+You should see Claude use 5 tool calls in sequence. The final output
+includes a directory tree and file contents:
+
+```
+project-scaffold/package.json
+project-scaffold/README.md
+project-scaffold/.gitignore
+```
+
+And the package.json contents:
+
+```json
+{
+  "name": "my-project",
+  "version": "0.1.0",
+  "description": "A scaffolded project created by Claude Code"
+}
+```
+
+**How you know it worked:**
+- A `project-scaffold/` directory exists with 3 files inside
+- You saw Bash (mkdir), Write (x3), Bash (find), and Read tool calls
+- No permission prompts appeared for these safe operations (they are pre-approved in settings.json)
