Implementation plan for the Donchian breakout candidate (parent spec docs/specs/0071-stage1-breakout.md). Four dependency-ordered tasks: RollingMax and RollingMin (monotonic-deque sliding extrema, mirroring the Sma/Delay node shape), a C2-causality + ±1-latch composition test, and the CLI breakout strategy (stage1_breakout_graph + manual-grid sweep family + --strategy/--channel wiring). refs #137
