Compare canonical repo paths when deciding to show provider

[Metastarx]

Summary

Comparing repositories in the analyze view could label two unrelated projects as the same repository. The provider suffix in the legend and tooltips was decided by checking whether one repo path appeared as an arbitrary substring of the other URLs, so "apache/dubbo" matched "apache/dubbo-go" and got rendered as "apache on Github" twice, while the same repo compared across github and gitee stayed unlabeled because a trailing slash or a different letter case broke the comparison. I added a canonical repo-path helper that reduces a URL to its lowercased namespace/repo pair, ignoring host, trailing slash, case and .git, and rewrote the check to compare those canonical paths for equality, only reporting a duplicate when the same path really appears under two different providers.
