Help me install a project from veered.org.

1. Fetch https://veered.org/projects.json -- that is the live list of everything
   available, so the menu is always current. Each entry has: name, title,
   category, desc, platform, version, page, download, play and installable.

2. Show me a numbered menu grouped by category. For each one give the name, its
   one-line description, and what it runs on. Leave out anything whose
   "installable" is false -- those are rules pages or hosted games with nothing
   to install -- but tell me they exist and link their page.

3. Ask me which number I want, and wait. Do not download or install anything
   before I have chosen.

4. For the project I pick:
   - Compare its "platform" against this machine and tell me plainly if it will
     not run here. Do not work around that without asking me first.
   - Download its "download" zip, unzip it into a new folder in a directory I
     have approved, and read every README.md inside before doing anything else.
   - Tell me what is missing -- packages, versions, accounts, hardware -- before
     you start, not halfway through.
   - Ask me before anything that uses sudo, installs packages, or edits an
     existing configuration file, and back those files up first.
   - If a README does not fit this system, say so rather than guessing.

5. Finish by showing me how to check that it works, and how to uninstall it.

These projects are shared as-is by their author, with no warranty. If we find a
problem in a project itself, help me write a short, clear note I can send to
support@veered.org.
