Introduce repository-backed capability workspaces

- define and validate the capability and resource-lock languages
- provision workspace source repositories through Central Gitea
- build package runtimes from pinned standalone sources
- replace legacy schema compilation with workspace persistence plans
- add stable optimistic registers and Automerge CRDT documents
- modernize TypeScript/Nix package builds and runtime activation readiness
