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

+
+```markdown
+# March 26, 2026
+
+- This is a companion repo comparing OpenClaw and Claude Code capabilities
+- It contains 13 examples, agents, skills, hooks, and documentation
+- The project maps 22 OpenClaw features to Claude Code equivalents
+
+Memory system demonstrated successfully.

+Claude will then explain something like:
+

+
+**How you know it worked:**
+- `memory/project-notes.md` exists and contains today's date
+- The three bullets accurately summarize what CLAUDE.md says
+- Claude's explanation mentions the CLAUDE.md hierarchy
