zebra-spaces: cache-busting meta on the HTML root

Browse source 
Browser HTML caching has been silently serving listeners old builds
even after deploy — log shows zero new-build markers from fox's
phone or laptop chrome session despite md5 matching on the
served file. Heuristic caching with no Cache-Control header gives
browsers freedom to keep the HTML for hours.

Adding the standard meta cache-bust triplet so the HTML is treated
as no-cache by every browser regardless of Caddy headers. JS / CSS
is inline so this covers the whole page in one go.
