✨ feat: add cost formatting for token usage

✨ feat: add cost formatting for token usage

🔧 Refactor:
- Imported CommitAnalyzer to facilitate cost formatting.
- Created a new function format_cost to handle cost representation.

💰 Update:
- Updated print_token_usage function to use the new format_cost method.
- Enhanced cost display for input, output, and total costs.

This update improves the cost representation in token usage summaries for better readability.
