feat: add auto_update config, clarify auto_install vs auto_update vs auto_check

- auto_install (default: true) — install missing binaries on register
- auto_check (default: true) — check for available updates periodically
- auto_update (default: false) — auto-update when newer versions found
- Disabling auto_check also disables auto_update
- Updated README and help docs
