Agent Skills: integrate-rate-limit

Integrate rate limiting into SvelteKit routes or ORPC handlers.

Update:

• Hook into rate-limit.ts instance
• Add rate limiter check before processing
• Throw appropriate errors for exceeded limits

Rate limiting conventions:

• Use 20 req/sec default based on rateLimiterMemory
• Differentiate by IP or session in production
• Handle rate-limit errors gracefully in UI
• Log or monitor excessive requests
