add pre-push deploy hook; source links to git.krz.sh; fix app button color

- pre-push hook builds with zola and rsyncs public/ to homelab on main
- wire core.hooksPath to tracked .githooks/
- point app source links at git.krz.sh instead of github
- keep .prose btn text at --text/--btn-fg instead of link blue
- drop dead github pages workflow (remote is self-hosted git now)
