Refactor Makefile to streamline build and run commands

- Updated the run command to execute the application from a built snapshot instead of using `go run`.
- Added a new run-debug command for running the application with debug logging.
- Consolidated the build process into a single target snapshot build command.
- Enhanced help output to reflect the new command structure.
