feat(python): add rye detector

[insign]

Adds support for the Rye package manager to the Python ecosystem detection logic.

1. Implemented Rye detection via pyproject.toml parsing for [tool.rye].
2. Added built-in commands parsing for Rye and custom script support via [tool.rye.scripts].
3. Updated main.rs to fix a clippy lint unnecessary_map_or.
