feat: add Learning Paths, examples, and project governance files

### New Content
- Learning Paths section in README (Junior/Senior/Power User/PM tracks)
- examples/ folder with 18 ready-to-use templates:
  - 4 agents (code-reviewer, test-writer, security-auditor, refactoring)
  - 2 skills (TDD workflow, security checklist)
  - 3 commands (commit, review-pr, generate-tests)
  - 4 hooks (bash + PowerShell for security, formatting)
  - 3 config templates (settings, MCP, gitignore)
  - 2 memory templates (project + personal CLAUDE.md)

### Governance
- CHANGELOG.md: Version history (1.0.0 → 1.1.0 → Unreleased)
- CONTRIBUTING.md: Contribution guidelines for community

### Documentation
- llms.txt: Updated structure with new files/folders

This update makes the guide more actionable with concrete templates
and provides clear learning paths for different skill levels.
