Summary

Update documentation to reflect the new EventBus-based monitoring architecture.

Parent Issue

• deps: Decouple monitoring integration via EventBus pattern #342

Depends On

• refactor: Define NetworkMetricEvent struct for EventBus-based metric publishing #343, refactor: Implement EventBus-based metric publishing in network_metrics #344, refactor: Remove KCENON_WITH_MONITORING_SYSTEM compile-time dependency #345, refactor: Update CMake to remove monitoring_system link dependency #346 (All implementation issues)

Files to Update

• docs/integration/with-monitoring.md
• docs/INTEGRATION.md
• README.md (if applicable)

Content to Add

1. Migration guide from KCENON_WITH_MONITORING_SYSTEM to EventBus pattern
2. Example of subscribing to NetworkMetricEvent from monitoring_system
3. Updated architecture diagrams
4. API reference for NetworkMetricEvent

Migration Guide Example

// Before: Direct monitoring_system dependency
#if KCENON_WITH_MONITORING_SYSTEM
auto collector = monitoring_system::get_collector();
http_client client(collector);
#else
http_client client;
#endif

// After: EventBus subscription
auto& bus = common::get_event_bus();
bus.subscribe<network::events::NetworkMetricEvent>(
    [](const auto& event) {
        // Process metric event
    }
);

Acceptance Criteria

• Migration guide complete
• Architecture diagrams updated
• All code examples tested
