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
+
+The pipeline takes 2-4 minutes. You will see agent invocations streaming:
+
+1. **Researcher agent** runs WebSearch and WebFetch (30-60 seconds)
+2. **Writer agent** produces a ~400-word draft (15-30 seconds)
+3. **Reviewer agent** critiques the draft (15-30 seconds)
+4. **Revision** if needed (15-30 seconds)
+5. **File writes** to pipeline-output/ and memory/
+
+When complete, two new files exist:
+
+`pipeline-output/permission-modes.md` (the article):

+- **Topic:** How Claude Code handles permission modes
+- **Word count:** 412

+
+**How you know it worked:**
+- Both files exist in the expected directories
+- The article is accurate (check against `security/permission-modes-explained.md`)
+- The pipeline log has today's date and a word count
+- You saw three distinct agent invocations in the terminal

 ## Why This Matters
 
 This is what Claude Code looks like as an actual agent platform, not a
