Show the build's commit in the page footer

Workers can't shell out at request time, so the commit has to be baked
in before wrangler bundles the sources. compile-views.ts grows a second
job and becomes scripts/build.ts: alongside the precompiled views it
writes src/commit.generated.ts with `git describe --tags --always
--dirty`, which yields a bare short hash until the repo is tagged and
marks builds made from an unclean working copy.
