Module blast_radius 

Defeasible Cascade Blast Radius Calculator (#336).

Replaces coreason_runtime/execution_plane/blast_radius.py.

Computes the propagation blast radius when a belief node is defeated in the epistemic knowledge graph. Tracks cascade depth and affected nodes for rollback planning.

Zero Waste: Delegates all graph traversal to petgraph (OSS). We only write the domain-specific defeasibility scoring logic.
