Named Connectable Apps

Registry rows for product names the screen already knows — no model.

The Connections panel opens on a first screenful (the products the product's own jobs plug into) so it is never empty while the model-named shelf is being built, 6-10s cold. Those are NAMES; this turns them into the registry's own apps in one request: the real slug (Xero is xero_accounting_api), the registry's mark, and own_door for an app that has a door of its own and must not be offered through this one. A name the registry does not carry is absent — the registry stays the only truth about which apps exist — and each row says which name asked for it (asked).

Unlike connect/apps this never falls back to the intent lane: a name that misses is a miss, not a phrase to interpret, so it costs no model call and the lookups are the registry's own one-hour cache.
