Merge master; OpenFleet keeps its name, PR 177's rental descriptor becomes OpenRental

PR 177 shipped a second OpenFleet under the same slug: a published listing of OpenAgent profiles and ipfile swarms with CoinPay rental offers. Anthony ruled that OpenFleet means the human-controlled fleet and the record of who spawned whom, so the rental contract is renamed OpenRental (slug openrental, catalogs family, group noun listing): docs/openrental.md, logicsrc-openrental.schema.json with type logicsrc.openrental and scope kind listing, fixtures/openrental, createOpenRental and OpenRental* types in the SDK, the openrental validator kind. Minor bumps because an export moved: @logicsrc/schemas 0.2.0, @logicsrc/validators 0.2.0, @logicsrc/sdk 0.2.0. The discovery contract test now covers openfleet, openrental and openwall, one per family, and accepts a landing-page link in llms.txt.

+npm install @logicsrc/sdk @logicsrc/validators

+
+```ts
+import { createOpenRental } from "@logicsrc/sdk";
+import { validate } from "@logicsrc/validators";

+const listing = createOpenRental({

+  }]
+});
+
+const result = validate("openrental", listing);

+
+Use `@logicsrc/validators` 0.2.0 or newer for OpenRental validation. See the
+[OpenRental specification](https://logicsrc.com/docs/openrental) for member
+bindings, exact decimal rental rates and CoinPay settlement metadata.
