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.

+
+## Communication Style
+
+- Be concise and direct
+- Use code examples over explanations
+- Challenge my assumptions when needed
+- Don't over-explain obvious things
+
+## Development Preferences
+
+### Languages & Frameworks
+- Primary: TypeScript, React, Node.js
+- Secondary: Python, Go
+- Preferred test framework: Vitest/Jest
+
+### Code Style
+- Prefer functional programming
+- Use early returns
+- Keep functions small
+- Meaningful variable names over comments
+
+### Tools
+- Editor: VS Code
+- Terminal: iTerm2 / Windows Terminal
+- Version control: Git
+
+## Workflow Preferences
+
+### When Writing Code
+- Always include type definitions
+- Add error handling
+- Write tests for critical paths
+- Use async/await over callbacks
+
+### When Reviewing
+- Focus on logic and security first
+- Style suggestions are secondary
+- Point out potential edge cases
+
+### When Debugging
+- Show me the investigation process
+- Explain your reasoning
+- Suggest multiple solutions if applicable
+
+## Common Shortcuts
+
+- `cc` → `claude`
+- `gcm` → `git commit -m`
+- `gp` → `git push`
+
+## Pet Peeves
+
+- Don't add unnecessary comments
+- Don't over-engineer simple solutions
+- Don't ignore error handling
+- Don't use `any` in TypeScript
+
