Semantic scene hook unavailable

The default RuntimeHooks::scene cannot answer semantic scene queries. The bridge returns a diagnostic instead of scene data.

#Common causes

• The runtime has not installed a scene-query integration.

#Fixes

• Implement RuntimeHooks::scene through ara-sim with a validated, read-only semantic query.

• Code: ARA-EXP-BRG-012 (slot 8088)
