feat(cli): introduce hdg global CLI tool with self-install, self-update and shorthand syntax

- hdg: Global executable with auto-symlinking to /usr/local/bin, self-update, and auto-setup

- cli.py: Unified Python CLI with setup, repair, doctor, update, and install commands

- add-gunicorn-service.sh: Kept as backward-compatible wrapper redirecting to hdg

add-gunicorn-service.sh
