chore: upgrade @automerge/automerge to 3.2.6 across npm workspace

Automerge 2.x's uncompressed in-memory representation could OOM the WASM
instance during loadIncremental (intermittent 'Unreachable code should not
be executed' on project open, requiring a page refresh); automerge 3 keeps
the compressed representation at runtime. Also declares hub-client's
previously-undeclared direct dependency on @automerge/automerge.
