fix: relax openai version constraint to allow newer SDK versions

[devin-ai-integration]

Summary

Fixes #4300 - The openai dependency was pinned too strictly (~=1.83.0 which resolves to >=1.83.0,<1.84.0), causing dependency resolution failures when users try to install CrewAI alongside packages that require newer OpenAI SDK versions (e.g., langchain-openai>=1.0.3 requires openai>=1.109.1).

This PR relaxes the constraint to >=1.83.0,<2, allowing any 1.x version while protecting against potential breaking changes in a future 2.0 release.

Changes:

• Updated openai dependency from ~=1.83.0 to >=1.83.0,<2 in lib/crewai/pyproject.toml
• Added two compatibility tests that verify all OpenAI SDK imports used by CrewAI are available
• Regenerated uv.lock

Review & Testing Checklist for Human

• Verify the version constraint is appropriate: The upper bound <2 assumes OpenAI SDK 2.0 (if/when released) may have breaking changes. Confirm this is the desired behavior.
• Test with a newer OpenAI SDK version: Install a version like openai>=1.90.0 and run the test suite to verify actual compatibility, not just import availability.
• Review uv.lock changes: The lock file was regenerated and includes many transitive dependency updates - verify these are acceptable.

Recommended test plan:

# Install with a newer openai version to verify the fix works
uv add "crewai[tools]" "langchain-openai>=1.0.3"
# Run the new compatibility tests
uv run pytest lib/crewai/tests/llms/openai/test_openai.py::test_openai_sdk_imports_compatibility lib/crewai/tests/llms/openai/test_openai.py::test_openai_sdk_client_instantiation -v

Notes

• The new tests serve as a "canary" to detect if a future OpenAI SDK version removes any types/classes that CrewAI depends on

Note

Medium Risk
Broadens the allowed openai SDK range, which could expose the project to subtle API behavior changes across 1.x versions despite added canary tests.

Overview
Relaxes the openai dependency constraint in pyproject.toml from a tight ~=1.83.0 pin to openai>=1.83.0,<2 to allow newer 1.x SDK versions.

Adds two new OpenAI SDK “canary” tests in tests/llms/openai/test_openai.py that validate key CrewAI-used imports remain present and that OpenAI/AsyncOpenAI clients still instantiate with expected chat.completions surfaces.
