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.

Model: opus-5-5
