chore: optimize pnpm cache configuration (elizaOS#2555)

- Move pnpm setup before cache configuration
- Add architecture-specific cache keys
- Include package.json in cache key for better specificity
- Add explicit store-dir configuration
- Improve restore-keys with more specific fallbacks

This change aims to improve package reuse during installation while maintaining existing functionality.
