fix(docker): use pnpm deploy for embedder runtime image

Browse Source 
The previous Dockerfile copied apps/embedder/node_modules straight from
the deps stage, but with pnpm's default isolated layout that directory
is a farm of relative symlinks pointing into the root .pnpm store. With
the root node_modules absent in the runtime image, every dependency
resolution failed (fastify, @xenova/transformers, ...).

pnpm deploy --prod writes a portable directory with flat node_modules
that resolves cleanly from a fresh WORKDIR. The `files` field on the
embedder package opts dist/ into the deployed output (the workspace
.gitignore would otherwise exclude it).
