[ Performance Improvement] Optimize generate Command Execution Speed

[Tanmayshi]

Why do we need this improvement?

The asyncapi generate command takes significantly longer to execute, especially on the first run. Benchmarking shows that the first execution can take up to 58 seconds, while subsequent runs are much faster (~4-10s). This suggests potential inefficiencies in caching, dependency resolution, and processing.

How will this change help?

Reduce execution time for generate command, improving usability.
Improve caching strategies to prevent slow first-run execution.
Enhance dependency management for a more optimized installation.
Potential migration to Bun or pnpm to speed up package res

How could it be implemented/designed?

✅ Profile command execution: Identify slow areas using benchmarking tools like Hyperfine.
✅ Optimize AsyncAPI processing: Investigate parallel execution, lazy loading, or caching.
✅ Improve dependency management: Reduce redundant dependencies & optimize imports.
✅ Explore Bun/pnpm migration: Evaluate if switching from npm to Bun or pnpm improves performance.

This is also a major task for gsoc project, we can consider this during that time
