fix(workflows): fail cleanly on unparseable catalog install URLs

urlparse raises ValueError on e.g. an unbalanced IPv6 literal before the
invalid-URL branch is reached; on workflow update that also bypassed the
per-workflow handler and aborted the whole command. Convert the parse
failure into a clean error so add fails cleanly and update skips just the
affected workflow.
