Subject: [PATCH] feat: Migrate C starter template to CMake and C23

This commit updates the C starter template to:
- Switch from gcc to CMake for build system
- Update to C23 language standard
- Restructure project layout from `app/` to `src/`
- Add vcpkg configuration for potential future dependencies
- Update compilation and run scripts to use CMake
