CodeRabbit Review Handler

Process CodeRabbit review comments with context-aware discretion.

Instructions

1. Initial Context

Inform the user:

I'll review the CodeRabbit comments with discretion, as CodeRabbit doesn't have access to the entire codebase and may not understand the full context.

For each comment, I'll:
- Evaluate if it's valid given our codebase context
- Accept suggestions that improve code quality
- Ignore suggestions that don't apply to our architecture
- Explain my reasoning for accept/ignore decisions
