fix(collab-doc): copy the full yjs/lib0 stack into the app image

The seed/merge/persist routes run the converter (markdown <-> Yjs) server-side. yjs is a
serverExternalPackage and the Next standalone tracer copies lib0 only partially — it drops the
ESM subpath file lib0/logging.js that yjs.mjs imports via lib0's exports map, so the seed 500s
('Cannot find module lib0/logging') and every collaborative doc is stuck read-only. Verified in
the running dev container: /app/node_modules/lib0 had 37/38 files, logging.js missing.

outputFileTracingIncludes can't fix it — its globs resolve against apps/sim, but these deps hoist
to the monorepo-root node_modules, so the glob matches nothing (my prior next.config attempt was a
no-op; reverted). Instead COPY the complete lib0/yjs/y-protocols from the deps stage in the runner,
overwriting the partial trace — the same pattern already used for isolated-vm.
