1.9.0

Lockstep with com.extentos:glasses:1.9.0 on Maven Central.

Adds OpenAI's two newest realtime models to the assistant catalog:

• gpt-realtime-2.1 — drop-in successor to gpt-realtime-2: same voices, same reasoning.effort knob, same pricing.
• gpt-realtime-2.1-mini — distilled reasoning at mini pricing. Despite the name it is not a newer gpt-realtime-mini: it does accept reasoning.effort (the older mini does not) and carries the full 128k context window (the older mini is 32k).

No Swift API change — the only diffs are Package.swift (binaryTarget url + checksum) and the regenerated bindings' doc comments. The default realtime model remains gpt-realtime-2, so upgrading moves no project onto a new model.
