- Add KCENON_WITH_MONITORING_SYSTEM macro definition with default value 0 - Add has_monitoring_system() constexpr helper function - Consistent with existing KCENON_WITH_NETWORK_SYSTEM pattern Refs #190
- Add static constexpr bool is_available to http_transport - Add static constexpr bool is_available to websocket_transport - is_available = true when KCENON_WITH_NETWORK_SYSTEM is enabled - is_available = false for stub implementations - Enables compile-time detection of transport availability Refs #190
- Add static constexpr bool is_available to message_bus_collector - is_available = true when KCENON_WITH_MONITORING_SYSTEM is enabled - is_available = false for stub implementation - Enables compile-time detection of monitoring availability Refs #190
- Add 'isolated' configure preset with all optional deps disabled - KCENON_WITH_NETWORK_SYSTEM=OFF - KCENON_WITH_MONITORING_SYSTEM=OFF - Add corresponding build and test presets - Enables verification that fallback implementations work correctly Refs #190
- Add script to verify isolated build works correctly - Configures and builds with all optional deps disabled - Runs tests to verify fallback implementations - Supports --clean and --skip-tests options Refs #190
- Add KCENON_WITH_MONITORING_SYSTEM to build options table - Add Optional Dependency Matrix section with fallback behaviors - Document is_available constexpr usage with code examples - Add Isolated Build section with preset usage instructions - Reference verify_isolated_build.sh script Refs #190
