Module health 

Health check endpoint helpers for operations.

Provides standard health check patterns:

• Basic health: returns {"status":"healthy"} on GET /health
• Detailed health with named checks, critical flags, and per-check latency
• Kubernetes-style liveness (/healthz) and readiness (/ready) probes

Example

use fastapi_core::health::{HealthCheckRegistry, HealthStatus};

let mut registry = HealthCheckRegistry::new();
registry.add("database", true, || async {
    // Check database connection
    Ok(())
});
registry.add("cache", false, || async {
    // Check cache connection (non-critical)
    Ok(())
});

let result = futures_executor::block_on(registry.check_all());
assert_eq!(result.status, HealthStatus::Healthy);
