A registry record is a name and a catalog

`config` — added this morning in 2.1.0 — is gone, and `storeRepositoryUrl` with it, along
with the two store repositories they pointed at.

2.1.0 had the registry say how each store behaves. Wrong shape: how a store behaves is
fixed per installed client, and this application is the only thing that can see the
machine it runs on. A copy of that on a server was a second authority over decisions this
side had already made correctly — including which directories the store may delete from —
and two authorities are a way to disagree.

Keeping two stores on one machine apart needs none of it. It is a subfolder, derived here:
the store id is a slug of the catalog host, the home is `<id>-desktop`, the games folder is
`<id>`, and that folder is the only subtree the store will ever delete from. Derived from
the *catalog* on purpose — the catalog is what a store is, so two records naming the same
one are the same store and land in the same place, which makes installing twice idempotent
instead of a way to orphan what is already there.

Existing installations keep their identity: a store home is recognised by its own
`config.json`, so one installed as `ttg` stays `ttg` in `ttg-desktop` with its games where
they are. Only a new install derives its id.

`StoreProvisioningService` no longer re-reads the registry before installing. That existed
to keep the renderer from supplying a config, and with no config in the record there is
nothing left to protect: a name and a catalog have no paths in them.
