/**
 * A browsable URL for the configured remote, or `null` when there isn't one.
 * A bare repo on disk is a valid sync target, so a local path -- and anything
 * else that doesn't parse -- stays plain text rather than becoming a dead link.
 *
 * An http(s) remote is already browsable, so it is reused as-is apart from the
 * `.git` suffix and any embedded credentials, which keeps forge-specific paths
 * (Azure's `org/project/_git/repo`) and non-default ports intact. Other schemes
 * -- `ssh://`, `git://`, `git@host:owner/repo` -- carry no browsable form, so
 * they are rebuilt over https from the parsed host and repository.
