Detailed Description

Zero-heap telemetry math helpers (PC_ENABLE_TELEMETRY).

Pure-computation building blocks for turning a stream of sensor samples into dashboard figures, alert triggers, and odometer-style totals - no heap, no Arduino dependency, all state in caller-supplied storage or small POD structs, so the whole cluster unit-tests on the host:

• pc_window moving-window statistics (mean / variance / stddev / min / max) over a caller-provided ring buffer, O(1) mean/variance via running sums.
• pc_rate derivative / rate-of-change between successive samples (units per second), for slope alerts.
• pc_totalizer trapezoidal integration of a rate over time (a running total / odometer).
