forked from Mxmilu666/frp
The Run() method had two nearly identical loop blocks for registering custom domains and subdomain, with the same group/non-group registration logic copy-pasted (~30 lines of duplication). Consolidate by collecting all domains into a single slice first, then iterating once with the shared registration logic. Also fixes a minor inconsistency where the custom domain block used routeConfig.Domain in CanonicalAddr but the subdomain block used tmpRouteConfig.Domain.
