fix: normalize ssh URL remotes in global discovery

Handle URL-style SSH git remotes such as ssh://git@github.com/owner/repo.git in the same canonicalization path as scp-style SSH remotes. This prevents global discovery consumers from reporting duplicate repos when different tools or clones use equivalent SSH remote formats.

Add regression coverage for GitHub and GitLab URL-style SSH remotes and for deduping SSH URL, scp-style SSH, and HTTPS forms together.

Fixes #975
