Summary

The API now accepts gpt-6.1-terra for OpenAI CUA (hyperbrowserai/browserctrl#1672). This PR adds it to the SDK's CuaLlm literal.

Changes

• Add "gpt-6.1-terra" to CuaLlm in hyperbrowser/models/consts.py
• Add gpt-6.1-terra to the GPT-6 CUA model test, and use it in the typecheck fixture in tests/typecheck/valid_requests.py
• Bump the version to 1.14.1

client.agents.cua.start({"task": "...", "llm": "gpt-6.1-terra", "reasoning_effort": "max"})

Validation

• ruff check hyperbrowser tests/test_cua_models.py
• pytest tests --ignore=tests/sandbox/e2e (1001 passed, 4 skipped)
• pytest tests/test_typed_request_surface.py tests/test_typing_contract.py with mypy 1.14.1 and Pyright 1.1.411 (9 passed)

Note

Low Risk
Constant and typing-only SDK change with no runtime logic; risk is limited to clients now passing a new llm value through validation.
