### Issue 1
examples/2.2.x/client-android/java/account/create-o-auth-2-session.md:19
This example calls `List.of(...)`, but its import block does not import `java.util.List`. Copying the snippet therefore fails to compile with `cannot find symbol: List`. This affects dozens of the new Android Java snippets, including `account/update-prefs.md`, which omits `java.util.Map`, and `vectorsdb/upsert-document.md`, which omits both collection imports. The generator should add the required imports throughout the 2.2.x Android Java examples.

Summary

This PR adds the version 2.2.x OpenAPI specification and a large generated set of SDK, REST, GraphQL, and CLI examples.

• Introduces the 2.2.x API contract.
• Adds examples across client, server, console, and mobile SDK targets.
• One widespread Android Java generation defect leaves collection types unimported, making affected snippets fail to compile when copied.
