test(create): snap-test the bundled-monorepo create.defaultTemplate path

End-to-end coverage for the gated injection: scaffolding from a
`monorepo: true` manifest entry must wire `create.defaultTemplate`
back to the org scope, and must run the lifted git-init prompt.

The new fixture ships a minimal `@your-org/create@1.0.0` tarball
containing a `templates/workspace/` directory with a workspace-style
`package.json`, `pnpm-workspace.yaml`, and a `vite.config.ts` that
deliberately omits a `create:` block. The test runs
`vp create @your-org:workspace --no-interactive --directory my-mono`
through the shared `.shared/mock-npm-registry.mjs` and then asserts:

- `my-mono/vite.config.ts` has `create: { defaultTemplate: "@your-org" }`,
- `pnpm-workspace.yaml` survives `rewriteMonorepo` post-processing,
- `my-mono/.git` exists (git-init unification covers this path).
