ci: deploy slides to gh-pages on push to main; serve helper
- pages.yml renders the 2026-Q2 deck with mdslides, stages a gruvbox landing page that links into each event, and ships it via actions/deploy-pages so every push to main republishes the site (Pages source must be set to "GitHub Actions" in repo settings once) - build-slides.sh learns --serve [port]: actually starts python3 -m http.server on the first free port and prints the URL, removing the "you have to copy this command yourself" footgun that broke the local preview - restore the per-event .gitignore rules that got lost in the move so target/, gpui-component/, and slides/ don't show up untracked Signed-off-by: Sven Kanoldt <sven@d34dl0ck.me>
