Migrate deploy branch to waveslab.org and add rsync deploy workflow

[kcaylor]

Summary

Migrate the deploy branch site configuration and content away from legacy caylor.eri.ucsb.edu URLs to waveslab.org, and add a production deploy workflow for self-hosted rsync deployment.

Config

• _config.yml: updated url to https://waveslab.org and set baseurl to "".

Templates

• No template files required changes in _includes/ or _layouts/.
• Verified canonical/Open Graph/Twitter/feed-related template logic already uses site.url/absolute_url and contains no hardcoded waves.eri.ucsb.edu or caylor.eri.ucsb.edu domains.

Content

• _pages/postdocs_2018.md: replaced legacy domain mentions with {{ '/' | absolute_url }} and converted riparian project link to internal {% link _posts/2018-01-28-funding-new-awards-for-riparian-ecohydrology.md %}.
• _people/chang.md: converted old-domain links to internal links ({% post_url 2016-02-14-elliot-changs-1st-paper-featured-on-the-cee-website %} and _people/wolf.md).
• _people/duwan.md: converted Cynthia profile link to internal _people/gerlein-safdi.md.
• _people/odonnell.md: converted Elliot profile link to internal _people/chang.md.
• _people/sinkler.md: converted Cynthia/Adam links to internal _people/gerlein-safdi.md and _people/wolf.md.

• _posts/2015-03-03-pulsepod-wins-third-place-at-the-keller-centers-10th-annual-innovation-forum.md: converted old-domain Kelly profile links to internal _people/caylor.md links.
• _posts/2015-04-14-4344.md: converted AAAS old-domain URL to internal {% post_url 2015-02-24-aaas-session-on-new-earth-observing-methods %}.
• _posts/2015-04-14-new-paper-in-ecosphere.md: converted old-domain publication URL to internal _publications/Gower2015_4364.md.
• _posts/2016-06-23-frances-odonnell-starting-as-assistant-professor-at-auburn-university.md: removed old-domain host from header.teaser and image src (migrated to root-relative /wp-content/... paths).
• _posts/2016-07-14-cynthia-gerlein-safdi-receives-mary-and-randall-hack-69-graduate-award.md: converted old-domain image URL to local {{ '/assets/images/pei_stacked_logo-1.jpg' | absolute_url }}.

CI/CD

• .github/workflows/deploy.yml (new):
  • Trigger on push to deploy
  • ubuntu-latest runner
  • Install Ruby + Bundler, run bundle install
  • Build with JEKYLL_ENV=production bundle exec jekyll build
  • Verify build output (_site/ and _site/index.html) before deploy
  • Deploy _site/ via rsync over SSH using secrets:
    • DEPLOY_SSH_KEY
    • DEPLOY_HOST
    • DEPLOY_USER
    • DEPLOY_PATH
  • Concurrency lock to prevent racing simultaneous deploy pushes

Validation

• Comprehensive grep for waves.eri.ucsb.edu across *.md, *.html, *.yml, *.yaml, *.css, *.js, *.json, *.xml, *.txt, and Gemfile: no matches.
• Checked for CNAME: not present.
• Checked for robots.txt, sitemap.xml, and feed.xml templates: not present in repo.
• Local bundle exec jekyll build could not be completed in this environment due local Ruby/Bundler mismatch (ruby 2.6.10; lockfile expects Bundler 2.7.2 and gem requirements include Ruby >= 2.7).
