docs(cubecow): remove License section from README

[lisongqian]

The "## License" section (MIT) has been removed from cubecow/README.md
since licensing is tracked elsewhere in the repository and the section
duplicated information that does not belong in the per-crate README.

Summary

This PR removes the ## License section from cubecow/README.md, which previously stated the crate was licensed under MIT.

Observations

The change is correct and should be merged. A few points worth noting:

1. The License section was factually wrong. The root LICENSE file declares the project as Apache-2.0, not MIT. Removing the section eliminates this misinformation.

2. Other crate READMEs handle this differently — agent/README.md and CubeShim/README.md include a License section that correctly says "Apache-2.0 — see LICENSE for details." Both approaches (omit entirely vs. link to root LICENSE) are defensible. The PR author's rationale that "licensing is tracked elsewhere" is valid, especially since the incorrect MIT text made removal the better call here.

3. Whitespace cleanup: The closing ``` of the preceding code block is properly added back, so no formatting breakage.

Verdict

✅ Approved — clean, single-purpose change with correct reasoning.
