Add deployment: Dockerfile, compose, proxy config, and docs

One container plus a Postgres behind any TLS-terminating proxy. Nothing is
specific to a particular host.

The app and API are served from a SINGLE origin. This is not tidiness: browser
auth sessions live in per-origin storage, so splitting them across two
hostnames makes sign-in loop in a way that presents as a server fault. The
short alias redirects rather than serving a second origin.

Two safety properties verified by running the image, not by reading the code:

- With NODE_ENV=production and no SUPABASE_URL, the process refuses to start
  and says why. Serving the whole CRM unauthenticated is a worse outcome than
  failing to deploy, so the failure is deliberate and loud.
- In production the development auth bypass does not apply: an unauthenticated
  request to /api/dashboard returns 401 rather than adopting the first user in
  the table.

The Dockerfile typechecks all six packages as a build gate, so a deploy that
does not compile fails at build time rather than in front of a user. Runtime
runs unprivileged as `node`, and Postgres is not published to the host.

Docs cover the ontology and why it is shaped this way, agent connection for
Claude Code / Codex / prime-agent / Buzz, and the provenance rules governing
seed data about real people — including how to have your record removed.

Verified: image builds, container reports healthy, serves the SPA, enforces
auth, and the production guard exits non-zero.

+# Deploying PIG
+
+PIG is one container plus a Postgres, behind any reverse proxy that terminates
+TLS. Nothing here is specific to a particular host.
+
+## 1. DNS
+
+Point the apex and `www` at the machine. Both must resolve before the proxy can
+obtain a certificate.
+
+```
+A   primeintellectgrowth.com       -> <your IP>
+A   www.primeintellectgrowth.com   -> <your IP>
+```
+
+## 2. Configuration
+
+```bash
+cp .env.example .env    # then edit
+```
+
+The values that must be set for a production start:
+
+| Variable | Why |
+|---|---|
+| `POSTGRES_PASSWORD` | Generate a fresh one; never reuse another service's |
+| `PIG_PUBLIC_URL` | The single origin the app is served from |
+| `SUPABASE_URL` / `SUPABASE_ANON_KEY` | Authentication. The app refuses to start in production without a Supabase URL, because it would otherwise serve the whole CRM unauthenticated |
+| `PIG_ADMIN_EMAILS` | Who may administer. **Every address here must already have an account** — an unregistered address listed as an admin is a standing offer of admin rights to whoever claims it first |
+
+Optional: `PRIME_API_KEY` (scope it to `Availability → Read` only),
+`PIGGY_ENABLED` + `ANTHROPIC_API_KEY`, and the Slack and Buzz credentials.
+
+## 3. Start
+
+```bash
+docker compose -p pig up -d --build
+docker compose -p pig exec app npx tsx packages/db/src/migrate.ts
+docker compose -p pig exec app npx tsx packages/db/src/seed/index.ts   # optional
+```
+
+Use `-p pig`. A compose project that shares a name with a neighbouring stack
+will adopt its volumes, which is a memorable way to lose a database.
+
+## 4. Reverse proxy
+
+See `Caddyfile.example`. Serve the app and API from the **same** origin.
+
+## 5. Verify
+
+```bash
+curl -s https://primeintellectgrowth.com/api/health
+# {"ok":true,"service":"pig","version":"0.1.0"}
+```
+
+## Upgrading
+
+```bash
+git pull
+docker compose -p pig up -d --build
+docker compose -p pig exec app npx tsx packages/db/src/migrate.ts
+```
+
+Migrations are additive and safe to re-run; Drizzle tracks what has been
+applied. Take a dump before a major upgrade anyway:
+
+```bash
+docker compose -p pig exec db pg_dump -U pig pig | gzip > pig-$(date +%F).sql.gz
+```
+
+## A note on the auth project
+
+PIG verifies JWTs but authorizes from its own `users` table. If the Supabase
+project is shared with another application, its users get **nothing** here until
+they are explicitly invited. That is deliberate, and it is why a valid token can
+still return `403 needs_profile`.
