Split the page shell out of the repository layout

layout.eta was two things at once: the HTML shell every page needs and
the repository chrome around it. owner.eta, being the one page that is
not about a repository, could use neither and carried its own copy of
the shell, which had drifted -- its footer named no build commit and
did not link to the original page on GitHub.

The shell moves to views/layouts/base.eta, taking its title and any
deferred scripts as layout data, and the chrome to views/layouts/repo.eta,
a layout over it that adds the clone commands, nav, search box, and the
"/" shortcut that focuses it. Repository pages point at repo.eta and
render as before; owner.eta uses base.eta directly and so gains the
footer it was missing.

Templates now live in more than one directory, so scripts/build.ts walks
views/ recursively and keys each template by its path underneath it.
Names crossing a directory are written from the views root
("/layouts/base.eta"), the one form both Eta's filesystem resolver and
the precompiled resolver in worker.ts agree on; siblings stay relative.
