fix(managed): compare retained declaring-type selection scope

Derive aggregate selected-scope agreement from retained nominal type identities instead of requested spellings. Keep incomplete or historical selected scope unknown while preserving caller selections, whole-inventory distinction, paging and member absence behavior.

Cover equivalent requests, same-label nested owners, missing and partial identity facts, and complete empty selections. Exercise CLI inspection Evidence through stdio MCP comparison after removing its selected source file.
