fix(plugins): cold-load partial tool registries

Fix plugin tool discovery when a selected wildcard plugin set is resolved against a partial active registry.\n\nRequire scoped registries to cover every requested plugin owner, force cold-load incomplete tool discovery registries without replacing active plugin runtime state, and add regression coverage for the partial-registry path.\n\nFixes #76780.\nThanks @lilesjtu.
