The /usage endpoints and dashboard was implemented by @Asheblog, thank you! (sorry I don't know why it's not showing)

Trying out AI generated changelog:

Changelog: v0.5.0 to v0.5.1

This update brings a new Usage Dashboard and minor fixes.

✨ New Features

• Usage Dashboard: Monitor your Copilot API usage and quotas via new GET /usage and GET /token endpoints. A dashboard URL now appears on server start.
• Token Visibility: A new --show-token flag lets you display GitHub and Copilot tokens during auth and start for debugging.

🚀 Improvements

• Error Logging: Improved HTTP error logging to include upstream JSON responses.
• Anthropic Compatibility: Corrected token usage reporting and content mapping for Anthropic API translation.

🛠️ Refactoring

• Code Structure: start command logic was moved to src/start.ts for better organization.
• ESLint: ESLint configuration now uses eslint.config.js instead of .ts.
