- Updated Gradle version in `.env`, Dockerfiles, and wrapper to 9.3.1. - Replaced alias-based application of `kotlinMultiplatform` plugin with direct `id` usage in subprojects to resolve "Plugin loaded multiple times" error. - Applied centralized plugin management and Gradle daemon optimizations to improve Docker build stability and address KMP classloading issues.
