Fix restore-dependencies requirements.txt parsing to handle inline comments

[tdowgielewicz]

Issue Description

This PR fixes a bug in the restore-dependencies command that occurred when a package in requirements.txt had an inline comment after the package name.

Previously, when executing python cm-cli.py restore-dependencies, the entire line (including comments) was passed to pip as the package name, causing installation failures. For example, a line like:

gdown # supports downloading the large file from Google Drive

Would result in the following error:

This issue prevented the installation of several custom nodes, including the GGUF node.

Solution

The fix adds proper parsing of package names by splitting at the # character and taking only the part before the comment. This ensures that only the actual package name is passed to pip during installation.

Impact

This change allows for more flexible requirements.txt files that can include inline documentation while maintaining compatibility with pip's package specification format.
