fix(gcloud): handle existing install, reduce output, fix PATH detection

- Add ~/google-cloud-sdk/bin to PATH at script start so existing
  installs are detected even when not in shell PATH
- Three-way check: gcloud in PATH → update, SDK dir exists → recover,
  neither → fresh install (avoids "directory already exists" error)
- Fresh install uses direct tarball + install.sh --quiet instead of
  the noisy sdk.cloud.google.com wrapper script
- Pipe update output through tail -1 to reduce noise
