Fix cargo warning about conflicting names between the cli and the oxen-py crate

[CleanCut]

Use a unique python name to avoid the warning from Cargo that the cli and oxen-py produce an artifact with the same name that will be disallowed in the future.

This doesn't change anything from a Python user's perspective. They will still do import oxen, as the python module is named oxen.

Walkthrough

This PR renames the Rust extension module from oxen to _oxen by updating the Cargo.toml library name and the #[pymodule] function, then updates all Python package imports across 10 files to reference the new module name.

Changes

Cohort / File(s)	Summary
Rust Module Definition crates/oxen-py/Cargo.toml, crates/oxen-py/src/lib.rs	Changed library name and pymodule function from oxen to _oxen.

Poem

🐰 A module once named just oxen plain,
Now bears a leading underscore's refrain,
With imports updated, from here to there,
The binding renamed with Python's flair! 🐍

Update imports in all diff/ files to use ._oxen module.

The change in oxen_fs.py is correct, but several files in the diff/ subdirectory still import from the old ..oxen module path:

• diff/diff.py (lines 39-40)
• diff/text_diff.py (line 1)
• diff/tabular_diff.py (line 1)
• diff/line_diff.py (line 1)

These imports will fail at runtime with ImportError since the old .oxen module no longer exists. Update them all to use ._oxen.
