ci: add Product CI merge gate and Autopilot auto-merge path

Aggregate lint, typecheck, builds, unit, Postgres journeys, and Web E2E
into a single Product CI check for branch protection. Soft-fail artifact
uploads and skip headless macOS screenshots so infra noise does not block
merge. Add autopilot/auto-merge workflow and MERGE_GATES.md.

+# CI merge gates
+
+This repository splits continuous integration into **product** checks that should block merge and **infra** checks that provide signal without blocking Autopilot merges.
+
+## Required for merge (product)
+
+Configure branch protection on `main` to require exactly one status check from the `ci` workflow:
+
+| Check name | Workflow | What it covers |
+| --- | --- | --- |
+| **Product CI** | `ci.yml` | Lint, Typecheck, Production builds, Unit tests, Postgres journeys, Web E2E |
+
+The aggregate `Product CI` job fails when any of those product jobs fail. Individual job names remain visible on the pull request for debugging.
+
+Optional but recommended repository settings:
+
+- Enable **Allow auto-merge**
+- Enable **Automatically delete head branches** after merge
+
+## Infra-only (never required)
+
+These workflows may fail without blocking product delivery. Do **not** add them to required status checks.
+
+| Check / workflow | Why infra |
+| --- | --- |
+| `macOS setup screenshot (infra)` (`desktop-macos-screenshot.yml`) | Native screenshot capture; skips when the runner has no display |
+| Playwright / desktop artifact uploads | Soft-fail (`continue-on-error`) when GitHub artifact quota is exhausted |
+| `publish-server-image.yml` (PR paths) | Docker image validation for infra changes |
+| `mobile Android screenshots` | Manual `workflow_dispatch` only |
+| `nightly verification` | Scheduled visual regression |
+| `manual topology verification` | Manual smoke |
+| `release-desktop.yml` | Tag-driven release pipeline |
+| `publish-playwright-report.yml` | Report publishing helper |
+
+## Autopilot auto-merge
+
+Workflow: `.github/workflows/autopilot-auto-merge.yml`
+
+1. Open a pull request from an Autopilot/cloud agent.
+2. Add label **`autopilot`** or **`automerge`**.
+3. Wait until **Product CI** is green on the head commit.
+4. The workflow runs `gh pr merge --auto --squash`. GitHub merges when branch protection is satisfied (required checks green, reviews if configured).
+
+### Dry-run mode
+
+Set repository variable `AUTOPILOT_MERGE_DRY_RUN` to `true` to log the merge command without enabling auto-merge.
+
+### Optional secret: `AUTOPILOT_MERGE_TOKEN`
+
+Most repositories can rely on the built-in `GITHUB_TOKEN` (`pull-requests: write`).
+
+Add a fine-grained PAT or GitHub App installation token as **`AUTOPILOT_MERGE_TOKEN`** when auto-merge is rejected because branch protection requires a human actor or bypass permission the default token lacks.
+
+Minimum scopes:
+
+- Pull requests: read and write
+- Contents: read (if merge commits need it under your rules)
+
+After adding the secret, remove `AUTOPILOT_MERGE_DRY_RUN` or set it to `false`.
+
+## One-time branch protection checklist (maintainer)
+
+1. Settings → Branches → `main` → Require status checks before merging.
+2. Search for **Product CI** and select only that check.
+3. Remove **macOS setup screenshot**, artifact-only jobs, and other infra workflows from required checks if they were added earlier.
+4. Enable **Allow auto-merge** if Autopilot should merge without manual clicking.
