distribution file-name
The distribution file name ({package}-{version}.tar.gz) is normalized by pdm and poetry. They replace '-' with '_'.

1. poetry: https://github.com/python-poetry/poetry-core/pull/484/files
2. pdm: https://github.com/pdm-project/pdm-backend/blob/abd5537cea74f79a2bdde0fb44fcd8a933522a0a/src/pdm/backend/utils.py#L35-L40
3. flit: https://github.com/pypa/flit/blob/d8cc776fd0312b4d0204e8b0b97d72977aa083a5/flit_core/flit_core/common.py#L439

Proposal

The naming convention of the package name released by the feeluown organization should use _ instead of - in its distribution filename.
