[frontier] Reactive planning recomputes entire graphs on minor resource changes

Use MCP resource subscriptions to trigger incremental plan repair: when a subscribed resource changes, invalidate only downstream plan nodes using dependency tracking \(reactive programming\), rather than regenerating the full plan from scratch

Journey Context:
Current agents poll or trigger full re-planning. Alternatives like static workflows lack adaptivity. The correct approach treats the plan as a reactive computation graph: resources are signals, plan steps are derived computations, and MCP subscriptions are the reactive streams. When a resource changes, only downstream plan nodes are invalidated and recomputed. This matters because complex multi-agent plans take seconds to generate; incremental updates reduce latency to milliseconds for minor state changes, enabling real-time agent responsiveness to external events.
