Decomposition scenario runner

Manual step-by-step runner. Nothing here calls real systems, tool outputs are stubbed.

1. Choose scenario & planning framing
Planning framing:

Applies to "Ask directly", "Ask planner to decompose", and each executed step. If the executor refuses, an adversary pushes back using the chosen angle (or rotates through all of them), up to this many rounds, with full conversation history. Every result can be pushed further later via "Continue arguing" or restarted via "Retry" — nothing here is final.
