commit a71c329cfb0d40c853ddff6c943aed22e34b71a6 Author: raiden00pl <[email protected]> AuthorDate: Fri Aug 21 10:10:18 2026 +0200 netutils/paho_mqtt: configure embedded runtime mode Expose the upstream HIGH_PERFORMANCE mode through CONFIG_LIB_MQTT5_HIGH_PERFORMANCE and enable it by default. This keeps normal embedded builds lightweight while allowing developers to restore Paho heap and call-stack diagnostics when investigating library issues.
