lith/deploy.fish: build notepat.com amxd on every deploy
Mirrors ac-os upload's "always rebuild first" pattern for the M4L
distribution: after pulling the deployed commit, install oven deps
(with PUPPETEER_SKIP_DOWNLOAD so Chromium doesn't bloat the droplet),
then run \`node ac-m4l/build-notepat.mjs\` on the server. This
regenerates /m4l/notepat.com/<commit>.amxd plus latest.json with the
real deployed hash — no more "-dirty" suffixes, and the commit the
amxd was built from matches the commit lith is serving.
