code-modernization: rate rules by what the system is for, and make live runs finish
Two problems from running the commands on real repositories: - The P0 definition was money- and regulation-shaped, so a music-library tool got no P0 rules and its behavior contract came out empty. P0 now means the system's core purpose depends on the rule, or a wrong result is costly or irreversible (money, legal, data integrity, security or safety, or the central calculation or decision the system exists to perform). - Citations came back as lists of ranges, and the rule renderer numbered RULE-NNN in a different order from the document. Each rule now cites one range and the numbers read in sequence. Commands that start subagents now say to run them in the foreground and wait, because a headless session ends when the model stops talking even if it said it was waiting for a background agent.
