Introduced a new "SGenOnly" build configuration across the solution, updating Directory.Build.props, AyCode.Core.targets, and the .sln file for full support. Centralized TargetFramework and build properties in AyCode.Core.targets, removing redundancy from project files. Updated code to recognize SGEN_ONLY at compile time. Added new Bash commands for file conversion and cleanup. No functional code changes outside build and configuration logic.
