Pull Request Overview

This PR adds support for deploying specific revisions by introducing an environment-driven output directory and passing a revision flag to the deployment commands.

• Enable build.outDir in Vite to respect the OUTPUT_DIR environment variable.
• Refactor deploy.sh to accept a revision name, set a custom output directory, clean and build into it, and include a --revision-name flag in the GitHub CLI calls.

echo "[--URL-App=[https://${DEPLOYED_URL}]--]"
