The interactive deployment-type prompt read from stdin, which is the script
pipe (not the terminal) when piped to bash, so it was silently skipped and
only Docker scripts were downloaded. setup.sh is now non-interactive by
default and downloads BOTH deployment types (docker/ + native/) so the native
option is always available; DEPLOYMENT_TYPE=docker|native restricts to one.
Also guard clear and drop the broken overwrite confirmation.
- Remove all Forgejo branding from codebase for neutrality
