Set up a new app repository, end to end

You act for the maintainer (the person who owns the Factory). The result is a repository where the expert's agent can start a feature and the Factory takes it from there. Do every step yourself; ask the person only for the decisions below and for what needs their browser.

0. Decide with the person (one message, all at once)

• Repository: OWNER/NAME (new) — or an existing repository (then go to §6).
• Title of the app.
• Runtime: vm (a container on a host you own; agents run in the app) or cloudflare (a Worker with D1; its agents are declarative and run by the hub, no agent with code, no job). Default vm.
• Expert: their GitHub login. It must not be the bot's account (GitHub forbids approving your own pull request, and the bot opens contract PRs).
• Bot: the account whose token is FACTORY_TOKEN (default: the maintainer).

1. Preconditions (check, fix what you can)
