Name each embedded static file so a missing Alpine.js fails the build (closes #166)

static/static.go embedded the css and js directories, which match
whatever is present, so a build that skipped make assets produced a
binary whose pages had no Alpine.js. It now names the four files the
pages load, so a missing one is a compile error naming it.
css/input.css, the Tailwind source that no page loads, is no longer
embedded or served.

Both lint stages now extract Alpine.js before linting, since the
static package no longer compiles without it.
