ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
numba 0.60.0 requires numpy<2.1,>=1.22, but you have numpy 2.2.1 which is incompatible.
Successfully installed morgul-0.1.0 numpy-2.2.1 typer-0.12.5 watchdir-1.0.0
```

on `pip install -e python-morgul`

使用 `pip install -e python-morgul` 重現回報的命令，然後檢查套件的相依性宣告以及回報的 NumPy/Numba 衝突。完成的標準是 editable install 不再產生不相容警告，同時保留必要的套件相依性。
