fix: v2.8.10 — the server starts again on plugin installs (js-yaml is a runtime dependency)

v2.8.9 crashed at start on every plugin install with "Cannot find module
'js-yaml'": server/lib/lane-detect.js requires it, but it was only a
devDependency that redoc used to pull in, and v2.8.8 dropped redoc. The
plugin installs with --omit=dev. This box hid it: Debian's global
/usr/share/nodejs has js-yaml. Reproduced with a pruned install and the
global paths off; fixed by moving js-yaml (and argparse in the lock) to
dependencies. New runtime-deps.test.js fails on any server/ require that is
not a dependency.
