Description

Define ConfigProtocol irpc service enum and ConfigServiceImpl behind the irpc feature flag, per ADR-030 and configuration.md.

ConfigServiceImpl wraps ArcSwap<DynamicConfig> and provides access to forwarding policy, rate limits, and reload capability. In Phase 1, direct ConfigReloadHandle::reload() is sufficient for minimal deployments. The irpc service provides the same functionality for production deployments.

Key additions:

• ConfigServiceImpl struct with forwarding_policy(), rate_limits(), reload() methods (always available, not feature-gated)
• ConfigProtocol irpc enum behind irpc feature: GetForwardingPolicy, GetRateLimits, ReloadForwarding, ReloadRateLimits

What stays the same: Direct ConfigReloadHandle::reload() is the primary API. ConfigServiceImpl is a thin wrapper over ArcSwap, also always available. The irpc service is additive.

Acceptance Criteria

• ConfigServiceImpl struct defined in crates/alknet-core/src/config/config_service.rs with methods per configuration.md
• ConfigServiceImpl reads from ArcSwap<DynamicConfig> and returns Arc<ForwardingPolicy>, Arc<RateLimitConfig>
• ConfigProtocol enum defined behind irpc feature flag
• Without irpc feature, ConfigServiceImpl is available for direct use
• With irpc feature, ConfigProtocol wraps ConfigServiceImpl
