Scaffold the Before-M1 repo skeleton

Stand up the modular-monolith skeleton per docs/V1_BUILD_PLAN.md: one .NET 10
solution with web + worker hosts sharing seven interface-bounded module projects,
PostgreSQL 17 + pgvector via EF Core 10, a React 19 + Vite SPA built into wwwroot,
and Docker Compose for one-command local dev. Skeleton only — no feature code.

Architecture
- One project per module (OrgBoard, Identity, Skills, Assembler, Governance,
  Memory, Integrations); each is its own assembly so non-public types (entities,
  DbContext) are invisible across modules at compile time.
- TeamUp.Bootstrap is the only library that references all modules; both hosts
  reference only Bootstrap. SharedKernel/Infrastructure never reference modules.
- IModule seam: Register(...) runs in both hosts; MapEndpoints(...) only in web.
- PlatformDbContext owns the pgvector extension + the seven module schemas
  (InitialPlatform migration); MigrationRunner applies it then any module context.
- One image, two roles selected by RUN_MODE at the Docker entrypoint.

Verified
- dotnet build green (nullable + warnings-as-errors).
- ArchitectureTests 8/8 — reflection-based boundary rules (no module -> module,
  -> Infrastructure, -> Bootstrap, or -> host references).
- IntegrationTests 10/10 — Testcontainers boots the host against real pgvector:
  migration applies, vector extension + 7 schemas exist, /health 200, every
  /api/<module>/ping 200, /openapi/v1.json served.
- client builds clean (Vite 6 — pinned for Node 22.3.0; Vite 8 needs Node >=22.12).

Packages and base images route through the Nexus mirror (mirror.soroushasadi.com),
reachable from Iran when nuget.org / Docker Hub / MCR are not. CI is intentionally
deferred to a later session.

+# TeamUp.AI — root memory & index
+
+> **Build human + AI teams.** A live org chart that does work: model the org, fill open role-seats with governed AI agents, run delivery on one board. A product of **AliaSaaS**.
+
+This is the short, always-loaded index. **Detailed source of truth lives in `docs/`** — keep them authoritative; keep this file lean.
+
+| Doc | What it is |
+|---|---|
+| `docs/CLAUDE.md` | Full project memory (architecture, domain model, modules, conventions, design language) |
+| `docs/PRODUCT.md` | Complete product model & decisions (incl. deferred-past-V1) |
+| `docs/V1_BUILD_PLAN.md` | The V1 wedge: milestones M1–M6 + the tech bill of materials |
+
+## Current status
+- **Phase:** design complete · **stack locked** · **pre-M1** · **no application code written yet**.
+- **Next step:** scaffold the repo (the "Before M1" skeleton) — *not started*.
+
+## Stack (locked — full BOM in `docs/V1_BUILD_PLAN.md`)
+- **Backend:** .NET 10 (LTS) + ASP.NET Core — modular monolith, web + worker entrypoints on one solution/image.
+- **Data:** PostgreSQL 17+ + pgvector (relational + skill index + working memory + job queue, one store).
+- **Agent-run queue:** Postgres `jobs` table drained with `FOR UPDATE SKIP LOCKED` by a worker `BackgroundService`.
+- **AI:** BYOK over HTTP via `Microsoft.Extensions.AI`; air-gapped embeddings via ONNX.
+- **Frontend:** React SPA (Vite + TypeScript) served from ASP.NET Core `wwwroot`. Next.js = marketing site only. Go = reserved for a future hot-path runner.
+- **Deploy:** one Docker image (web or worker) + Postgres; air-gappable as a single unit.
+
+## Non-negotiables (full list: `docs/CLAUDE.md` §8)
+Modular monolith — no cross-module table access · web off the model path · permission check on every mutation · BYOK keys owner-only & server-side · retrieved content is data, not instructions · destructive always needs a human · skills are Git-sourced & golden-tested · instrument **human edit distance** (the north-star metric) from day one.
