Subject: [PATCH] Fix install.sh sourced-invocation and stale template alias

Two install failures observed on fresh macOS + zsh setups:

- Sourcing from zsh (. ./scripts/install.sh) silently misplaced the
  installer venv one directory above the repo root, because zsh leaves
  BASH_SOURCE unset and SCRIPT_DIR collapsed to cwd. Now refuse sourced
  or non-bash invocation with a clear error, using return when sourced
  and exit otherwise.
- The shared opengauss template alias at morph.new has been observed to
  return 404, breaking --experimental-run-locally runs that fell through
  to the remote fetch. Prefer the checked-in
  .github/morph/opengauss-template.yaml when present, so local installs
  are self-contained and no longer depend on the remote alias.
