Code Review

This pull request introduces a get_version() helper function in agentevolver/__init__.py to expose the project's version. The implementation is straightforward. My review includes suggestions to improve the structure of the __init__.py file by adhering to PEP 8 for import placement and by explicitly defining the public API using __all__, which are common best practices for Python packages.

[gemini-code-assist]

To explicitly declare the public API of the agentevolver package, it's a good practice to define __all__ in the __init__.py file. This controls which symbols are imported when a user does from agentevolver import *. I suggest adding __all__ = ["get_version", "__version__"] before this function definition.

Suggested change

	def get_version():
	__all__ = ["get_version", "__version__"]
	def get_version():

[gemini-code-assist]

According to PEP 8, imports should be placed at the top of the file, after any module comments and docstrings, and before module globals and constants. Placing imports after function definitions can lead to confusion and potential circular import issues. Please move this import to the top of the file, before the __version__ assignment.
