feat(sdk): add lucy-vton-3.5 realtime and batch models

[AdirAmsalem]

What

Adds lucy-vton-3.5, the latest generation of the Lucy virtual try-on model, as a canonical model on both the realtime and batch/video surfaces. lucy-vton-latest now resolves to it, so callers on the latest alias get the newest quality automatically while lucy-vton-3 and lucy-vton-2 remain available by explicit name.

Why

Give SDK users access to the newest virtual try-on model without breaking anyone pinned to a specific prior version.

Usage

import { createDecartClient, models } from "@decartai/sdk";

const client = createDecartClient({ apiKey });

// Batch / video
const result = await client.queue.submitAndPoll({
  model: models.video("lucy-vton-3.5"),
  prompt: "Wearing a red leather jacket",
  data: videoBlob,
});

// Realtime
const realtime = models.realtime("lucy-vton-3.5");

Note

Low Risk
Additive model registry and type union changes with no auth or breaking renames; only behavioral shift is server resolution for lucy-vton-latest callers.

Overview
Adds lucy-vton-3.5 as a canonical virtual try-on model on realtime (/v1/stream) and queue/video (/v1/generate/lucy-vton-3.5, /v1/jobs/lucy-vton-3.5), wired through the model registry with the same videoEdit2 inputs and dimensions as lucy-vton-3 (1088×624).

Docs and comments now state that lucy-vton-latest resolves server-side to lucy-vton-3.5 (was 3); explicit lucy-vton-3 / lucy-vton-2 names stay unchanged. The SDK demo page adds a Lucy VTON 3.5 picker option; unit, queue e2e, and realtime e2e tests cover the new name.
