feat(http): reimplement CurlDownloader on reqwest; port 15 more tests

Replace the libcurl-shim CurlDownloader with a reqwest+tokio implementation per
the .ken sketch, resolving the construction panic that blocked command tests
(mock path via __new_mock is untouched). Port remote_filesystem (7), hg/svn
driver (4), zip_archiver/git_exclude_filter (4) tests. Fix hg/svn/git_exclude
regex-delimiter and svn result-propagation porting bugs.
