fix(scripts): lint-org pre-registers runtime org link types

mu4e registers its link type in a live Emacs, so batch org-lint parsed [[mu4e:msgid:...]] links as fuzzy heading refs and flagged "Unknown fuzzy location" on links that work interactively. lint-org now registers each type in lo-runtime-link-types as a no-op before linting. org-link-set-parameters merges rather than replaces, so a genuinely loaded mu4e keeps its real parameters.
