@cursoragent rebase on next then make sure to fix lint errors

[cursor]

Done.

• Rebasing onto origin/next completed cleanly.
• Pushed rebased branch cursor/sdk-cli-parameter-changes-de43.
• Updated PR target/base to next.
• No lint code fixes were needed after rebase.

Verified:

./scripts/lint
uv run ruff format --check
uv run pytest tests/cli/test_evals.py -n 0

All passed locally.

GitHub check status at last poll:

• lint: pass
• build: pass
• test-integration / test-others: still pending on the push run

Heads up: this cloud env was missing uv, so I installed it and synced deps. For future agents, env setup prompt could be:

Install uv in the Cursor Cloud environment and run uv sync --all-extras for togethercomputer/together-py so lint/test commands work out of the box.
