Switch production deployment from artifact-based Pages to a gh-pages
branch (peaceiris/actions-gh-pages), enabling PR previews to coexist
as subdirectories alongside the live site.
Add preview.yml: on every PR open/sync/reopen, builds Hugo with a
PR-specific baseURL and deploys to pr-preview/pr-{number}/ on the
gh-pages branch via rossjrw/pr-preview-action. The action posts a
comment on the PR with the live preview URL and cleans up the
subdirectory automatically when the PR is closed.

GitHub Pages needs to be told to serve from the branch instead of Actions:
GitHub Actions→Deploy from a branchgh-pages, folder:/→ SaveThe
gh-pagesbranch is created automatically the first time the updateddeploy.ymlruns onmain(i.e. when this PR merges). Once Pages is pointed at it, the production URLhttps://mathieson.github.io/blog/stays exactly the same.Generated by Claude Code
