Adds a workflow that builds the site on each PR and publishes it to
https://substrait.io/pr-preview/pr-<N>/so reviewers can see rendered changes before merging. Deploys are scoped to a subdirectory withkeep_files: trueso sibling previews and the production site root aren't disturbed. Closing a PR removes its preview directory and deletes the sticky comment.Reuses the existing
SUBSTRAIT_SITE_DEPLOY_KEY, so no new secrets are needed. As a consequence, fork PRs are skipped since GitHub doesn't expose secrets to fork-triggered workflows; adding fork support would require theworkflow_runtwo-workflow pattern and is left as a follow-up.Pushes to
mainstill overwrite the external repo root and will remove any active previews. Re-running this workflow from the Actions tab restores the preview for an open PR.Note: This PR was developed with AI assistance. All changes have been reviewed, and I take full responsibility for this contribution.
