Break the updated workspace vision into a checked-in roadmap from 2.4.0 through 3.1.0 so later implementation can be driven milestone by milestone.
Link the roadmap from the vision doc and keep each release slice scoped to one product capability, from the workspace contract pivot through shells, export/diff, services, snapshots, secrets, networking, and GA promotion.
This is a docs-only planning scaffold; runtime behavior stays unchanged in this commit.
