Subject: fix(net): handle remote archive URLs via tar/zip browse #38744

Problem:
Opening .tar.gz or .zip URLs shows raw binary instead of using the archive plugins.

Solution:
Similar to the original netrw implementation, the autocmd should detect
archive URLs, download them to a temp file and the open them with
tar/zip handlers already bundled as vim plugins.
