Make builtin potential list alphabetical (and simplify public API export??)

[adrn]

This first sorts the list of potential names alphabetically in the builtin __init__.py. I then also was puzzling at why we need another manual list of potential names in galax/potential/__init__.py for the public API -- it's annoying to have to maintain the list of names in so many places! Can we just dynamically add to __all__ like this, since anything exported at the builtin/__init__.py level should probably be public API anyway?

Pull Request Overview

This PR alphabetizes the builtin potential list and simplifies the public API export mechanism by dynamically adding builtin potentials to __all__ instead of manually maintaining duplicate lists.

• Sorts the __all__ list in builtin/__init__.py alphabetically for better maintainability
• Replaces explicit import and __all__ entries with a dynamic approach using from ._src.builtin import *
• Automatically extends the main __all__ list with builtin potentials to reduce duplication

Using wildcard imports (from module import *) is generally discouraged as it makes it unclear what names are being imported and can lead to namespace pollution. Consider using explicit imports or importing the module and accessing attributes through it.

Suggested change

	from ._src.builtin import __all__ as _builtin_all
	from ._src.builtin import __all__ as _builtin_all
	for _name in _builtin_all:
	globals()[_name] = getattr(__import__(f"{__name__}._src.builtin", fromlist=[_name]), _name)

[Copilot]

[nitpick] The expression __all__ = __all__ + list(_builtin_all) modifies __all__ after it's been defined, making the final exported API less obvious. Consider using __all__.extend(_builtin_all) for clearer intent, or define __all__ completely in one place.

Suggested change

	__all__ = __all__ + list(_builtin_all)
	__all__.extend(_builtin_all)

I like the idea of simplifying the __init__.py. But I think the public-facing one should have the statically defined list. This can be important for tools.
