searchMemoryWiki called sharedMemoryManager.search() and getMemoryWikiPage
called manager.readFile() with only a truthiness guard. A memory plugin
whose runtime returns a manager that does not implement the
MemorySearchManager contract crashed shared-backend wiki search with
"sharedMemoryManager.search is not a function" from inside the bundle --
@mem0/openclaw-mem0 <= 1.0.14 registered exactly such a partial manager
(status/probeEmbeddingAvailability/close only).
Guard both call sites and throw an actionable error instead: name the
missing contract method and point at search.backend="local" for wiki-only
access.
