Add Muse Wonder to Meta Computer Use models

[NikhilShahi]

Summary

Support muse-wonder-1.0 in Meta Computer Use requests through the existing MetaComputerUseLlm type.

Changes

• Add the model without changing request methods or defaults.
• Cover Wonder and Spark task lifecycle requests and responses, including max reasoning and custom Meta API keys.
• Bump the SDK to 1.2.1.

Validation

• yarn lint, yarn typecheck, and yarn build passed.
• yarn test: 732 tests passed.
• The Meta Computer Use Node quick-start example passed against a local HTTP fixture; no live agent task was run.

Note

Low Risk
Type-only model addition plus test updates; no changes to HTTP paths, defaults, or runtime agent logic.

Overview
Adds muse-wonder-1.0 to the MetaComputerUseLlm union so Meta Computer Use start requests can pass the new model through existing typed APIs (no client method or default changes).

Integration coverage is broadened by parameterizing the mock HTTP server on the returned step model and running the Meta Computer Use lifecycle test for both muse-spark-1.3 and muse-wonder-1.0.

SDK version is bumped to 1.2.1.
