refactor(minecraft): dead code cleanup

Strips saliency thresholds, window counters, signal generation, and route filtering from all perception event definitions and EventRegistry. Events now emit raw data directly via onRawEvent callback without conscious/reflex/debug routing or threshold-based filtering. Removes WindowCounter, SaliencySnapshot, and related timer/slot logic.
