The guard forced all cinematic output types to legacy dispatch because
BLENDER_CINEMATIC did not exist in the workflow graph. M1 added that node,
so the guard is now stale — it was preventing cinematic output types from
ever using graph mode even after an admin sets workflow_rollout_mode=graph.
The normal gate path handles it correctly: workflow_rollout_mode=legacy_only
keeps it on legacy, and find_unsupported_graph_nodes preflight catches any
workflow that doesn't actually contain a BLENDER_CINEMATIC node.
