data-service-proxy-direct
Create resilient data fetching services with circuit breaker pattern, supporting both proxied and direct API calls. Services handle fetch, cache, retry, and expose typed data to panel components.

# Data Service Pattern
Each panel's data comes from a dedicated **service module** in `src/services/`. Services handle API calls, caching, error handling with circuit breaker pattern, and can work with both proxied and direct API calls.
## Circuit Breaker
The circuit breaker prevents cascading failures when an API is down. After N consecutive failures, it enters "cooldown" mode and serves cached data instead of hitting the API.
Create `src/utils/circuit-breaker.ts`:
```typescript
interface CircuitState {
failures: number;
cooldownUntil: number;
