Clean up Module Developer agent - remove 5 C's references

- Removed optional 5 C's checkpoint section (unnecessary complexity)
- Fixed Build→Use→Reflect consistency (was mixing with Understand)
- Removed reference to MARKDOWN_BEST_PRACTICES.md (5 C's pattern)
- Updated anti-patterns to focus on standardized introduction format
- Improved test-immediately pattern with clearer requirements
- Simplified agent instructions for clarity and consistency

+- **Structure**: Add consistent patterns and clear organization
 - **Education**: Keep ALL explanations, examples, and context

-### The 5 C's as Optional Checkpoint
-The 5 C's can be used as a quick implementation checkpoint, but should NOT duplicate existing content:
-1. **Context**: Why are we doing this? (if not already covered)
-2. **Concept**: What is this technically? (if needs clarification)
-3. **Connection**: How does this relate to what they know? (if adds value)
-4. **Concrete**: Specific example with real values (if helpful)
-5. **Confidence**: What success looks like (if not obvious)

-**IMPORTANT**: If these topics are already covered in the module's educational sections, don't repeat them. The 5 C's is a tool, not a requirement.

+5. Run test at cell bottom with clear output
