fix(memory-wiki): skip bridge pruning when memory-core is not loaded (#71764)

When memory-core plugin is not registered (e.g. CLI context),
listActiveMemoryPublicArtifacts returns an empty array. The previous code
would then call pruneImportedSourceEntries with an empty activeKeys Set,
which removes ALL bridge-imported entries.

Now checks getMemoryCapabilityRegistration() instead of relying on artifact
count as a proxy, correctly distinguishing between 'plugin not loaded' and
'plugin loaded with no artifacts'.

Fixes #68373
