Update Zig version to 0.15 and refactor build configuration

- Changed minimum Zig version from 0.14.0 to 0.15.1 in build.zig.zon and codecrafters.yml files.
- Updated build.zig to use `createModule` for the executable's root module.
- Modified README.md and config.yml to reflect the new required Zig version.
- Adjusted script execution in run.sh and your_program.sh for better compatibility.
- Enhanced stdout handling in main.zig for improved output management.
