cmd/git(fix[GitRemoteManager.ls]): Handle URLs with spaces

why: The regex pattern used \S+ for URLs which failed to match
paths containing spaces (e.g., /tmp/foo bar), causing those
remotes to be silently dropped from the listing.
what:
- Change URL pattern from \S+ to .+? (non-greedy any char)
- Add line anchors (^ and $) for proper multiline matching
- Non-greedy ensures we stop at the (fetch|push) suffix
