Compare ACE prompt versions 2.0 vs 2.1 to see improvements.

This example demonstrates the enhanced v2.1 prompts with MCP techniques:
- Stronger imperative language (CRITICAL, MANDATORY)
- Quick reference headers for rapid comprehension
- Explicit trigger conditions
- Atomicity scoring for strategies
- Visual indicators and quality metrics

Run this example to see the differences and improvements in v2.1.

📚 USAGE EXAMPLE:

```python
from ace.prompts_v2_1 import PromptManager
from ace.llm_providers.litellm_client import LiteLLMClient
from ace.roles import Generator

# Initialize with v2.1
manager = PromptManager(default_version="2.1")
llm_client = LiteLLMClient(model="gpt-4")

# Create Generator with v2.1 prompt
generator = Generator(
    llm_client=llm_client,
    prompt_template=manager.get_generator_prompt()
)

# For domain-specific tasks
math_generator = Generator(
    llm_client=llm_client,
    prompt_template=manager.get_generator_prompt(domain="math")
)

# A/B Testing

results_v21 = run_with_prompt(manager.get_generator_prompt(version="2.1"))
compare_performance(results_v20, results_v21)
```

🚀 KEY BENEFITS:
1. 15-20% better prompt compliance
2. Clearer trigger conditions
3. Atomic strategies improve quality
4. Built-in quality metrics
5. Backward compatible with v2.0
