Remove local development README and enhance scripts for cross-platform compatibility

- Deleted `README.md` for local development setup as it was deemed unnecessary.
- Updated `setup-neon.sh`, `start-all.sh`, and `create-service.sh` scripts to source an OS helper for improved cross-platform command execution.
- Modified commands in `init-project.sh` to reflect the new script structure for starting services.
