feat(db): agentic-teams data model — epics, work items, repos, membership

Adds the foundation entities from docs/agentic-teams.md §5/§7: a versioned
vision layer (Epic -> EpicTask -> Task), git repositories attached to projects,
agents as many-to-many project members, and the ephemeral session that IS an
agent's workspace.

9 tables + 5 enums, purely additive — no drops and no column changes on
existing tables, since every new relation is held on the new side.

Shape notes:

- EpicTask chaining uses an explicit EpicTaskEdge table rather than a
  self-referencing array, so the roadmap graph walks in both directions and
  edges can carry a type later.
- TaskVerdict is commit-pinned and immutable: "QA verified 3f2ab" stays
  reproducible, which is what lets later coverage claims be audited rather than
  believed. TaskEvent is the append-only transition log.
- Task survives losing its repo and its assignee (both SetNull) — a work item
  outlives whoever happened to be working it — but cascades from its EpicTask.
- CodeRepo, not Repository: `repository.repository.ts` next to 24 other
  *.repository.ts data-access files would be actively confusing. CLI resource is
  `repos`, with repo/repository/repositories aliased onto it.
- AgentProject.llmId exists so the brain-ownership question
  (docs/agentic-teams.md §15 Q1) can be settled either way without a migration.
- Agent.projectId is retained and coexists with AgentProject for one release so
  findByProjectId / prepareContext keep working. Note this partially reverses
  20260223120000_remove_project_members — deliberately, and only for agents;
  human membership stays RBAC-driven.

No CHECK constraints anywhere, on purpose: deploy/entrypoint.sh provisions with
`prisma db push`, so hand-written migration SQL never runs in production. The
migration file is kept for local `migrate dev` parity and as a readable record,
and says so in its header. Invariants that cannot be expressed in the schema
(EpicTaskEdge cycle rejection) belong to the service layer; a schema test
documents that boundary rather than pretending the database enforces it.

Tests: 23 schema tests covering defaults, per-project name scoping, cascade vs
SetNull on every FK, all 12 lifecycle states, and the GC-sweep predicate.
clearAllTables extended for all 9 models.

Verified locally against postgres:16-alpine on :5433 — db suite 128 passed
(baseline was 105; the same 4 pre-existing Secret_backendId_fkey failures
remain, unrelated). Workspace 2291 passed, build clean, lint unchanged at the
repo's pre-existing 869.
