## What
Adds a `cloud` Playwright project so E2E tests can run against
`DISTRIBUTION=cloud` builds, with `@cloud` / `@oss` test tagging.
## Why
100+ usages of `isCloud` / `DISTRIBUTION` across 9 categories (API
routing, UI visibility, settings, auth). Zero cloud test infrastructure
existed — cloud-specific UI components (LoginButton, SubscribeButton,
etc.) had no E2E coverage path.
## Investigation: Runtime Toggle
Investigated whether `isCloud` could be made runtime-toggleable in
dev/test mode (via `window.__FORCE_CLOUD__`). **Not feasible** —
`__DISTRIBUTION__` is a Vite `define` compile-time constant used for
dead-code elimination. Runtime override would break tree-shaking in
production.

`research/architecture/cloud-runtime-toggle-investigation.md`
## What's included
### Playwright Config
- New `cloud` project alongside existing `chromium`
- Cloud project: `grep: /@cloud/` — only runs `@cloud` tagged tests
- Chromium project: `grepInvert: /@cloud/` — excludes cloud tests
### Build Script
- `npm run build:cloud` → `DISTRIBUTION=cloud vite build`
### Test Tagging Convention
```typescript
test('works in both', async () => { ... });
test('subscription button visible @cloud', async () => { ... });
test('install manager prompt @oss', async () => { ... });
```
### Example Tests
- 2 cloud-only tests validating cloud UI visibility
## NOT included (future work)
- CI workflow job for cloud tests (separate PR)
- Cloud project is opt-in — not run by default locally
## Unblocks
- Cloud-specific E2E tests for entire team
- TB-03 LoginButton, TB-04 SubscribeButton (@Kaili Yang)
- DLG-04 SignIn, DLG-06 CancelSubscription
