chore: improve crewAI maintenance path

[lphuc2250gma]

Summary:

• Add or tighten focused edge-case tests or type assertions in lib/cli/tests/test_cli.py, lib/cli/tests/test_git.py related to Python typing, tests, CLI ergonomics, observability; avoid docs-only changes and broad refactors.
• Keep the change narrow so it is straightforward to review.

Notes:

• I kept this scoped to the relevant implementation and tests.

Summary by CodeRabbit

• Tests
  • Added test coverage for handling missing Git remote configurations, ensuring the system properly returns null when the origin remote is not available.

📝 Walkthrough

Walkthrough

A new unit test case test_origin_url_no_remote was added to lib/cli/tests/test_git.py. The test verifies that the Repository.origin_url() method returns None when the origin remote does not exist, by mocking the git remote get-url command to fail with a non-zero exit code and "No such remote" error message.

Poem

🐰 A test hops in with care so true,
When remotes vanish and origins flee,
None is the answer we now pursue—
Coverage blooming, strong and free! 🌱

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Title check	❓ Inconclusive	The title 'chore: improve crewAI maintenance path' is vague and generic—it does not specifically describe the actual changes, which add a unit test for Repository.origin_url() behavior.	Revise the title to be more specific about the changes, such as 'test: add test for Repository.origin_url() when origin remote does not exist' to clearly communicate the primary change.
