What does this PR do?

Though it's still not the case in the install script, this change allows using set -euxo pipefail instead of solely set -e like current setup, for debugging purposes.

How did you verify your code works?

• Update the second line with set -euxo pipefail instead of set -e
• Run the script

📝 Walkthrough

Walkthrough

This pull request updates the get_latest_version function in install.sh to use parameter expansion ${VERSION:-} when testing whether the VERSION variable is set. The change replaces direct variable reference with a safer conditional pattern, ensuring the function correctly handles cases where VERSION is unset before falling back to GitHub API-based version lookup.
