v2 foundation: shared contracts, app profile schema, wiring stubs

- projects: app profile columns + one app per org; project_external_git,
  deploy_targets, org_model_grants tables (migration a0f0e1d2c3b4)
- ports + fakes: RepoWorkspace, DeliveryHooks, DeployTarget, Memory,
  ModelGrants, WorkforceBootstrap; AppProfile + AppProfileRepository
- per-workstream wiring (container_org/engine/delivery), config blocks,
  empty routers, delivery worker, MCP/delivery service shells, web stubs
- admin nav derives from ADMIN_ITEMS; plan docs updated for ext4 worktrees
