//! Foxhunt API Service — unified gRPC gateway with tonic-web for browser access
//!
//! Provides zero-copy gRPC proxying with:
//! - RBAC authorization with sub-100ns cached permission checks
//! - <10us routing overhead
//! - Connection pooling
//! - Circuit breaker pattern
//! - Health checking
//! - Performance monitoring
//! - Token bucket rate limiting with <50ns cache hits
//! - gRPC-Web support for browser clients via tonic-web
