ADR-0087 exemption (no-migration-prescription): No metadata moves: no spec key, authorable spelling, object or action definition or stored shape is added, removed, renamed or re-shaped, and no exported declaration is removed or narrowed, so there is nothing for `objectstack migrate meta` to rewrite. What changes is where the `/actions` door reads a standalone action's declaration: through the protocol's by-name `action` read, which already withholds a disabled package's item, so such an action resolves to no declaration. No function is added or published; `resolveRouteActionDeclaration` keeps its signature. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and nothing exported is removed or narrowed (not runtime-interface-only, type-surface-only or runtime-export-retired).
