feat(domains): two-path activation gate + both-faces slots (adr-077)

_dispatch_domain now activates a domain by EITHER a managed project's repo_kind
(adr-012) OR the presence of a bond carrier .domains-ontoref/<id>/bonds.ncl
(adr-073), with no manifest required on the bond path. The repo_kind path is
unchanged; the bond path is purely additive. domains/schema.ncl gains adrs/modes
reference-id slots so a domain carries both faces (adr-076 the-domain-scope-
carries-both-faces).
