Bug Fixes And Functionality Improvements

[qr243vbi]

Fixed builds in openSUSE and Fedora from generated specifications, added an option to retrieve metadata from the archive and local module, fixed code related to metadata processing, removed XML-RPC search, which is unavailable.

I would like to note that pypi-search is no longer available in the Python Package Index (PyPI), and the OpenSUSE package ‘python313-pypi-search’ does not work, so unit tests without these improvements will not be successful.
