An industrial-grade Model Context Protocol (MCP) server providing `compute_dfa_alpha1_aerobic_threshold`. Built with **100% pure Python standard library** (zero pip dependencies).

## Overview
Calculates short-term Detrended Fluctuation Analysis (DFA a1) fractal scaling of RR-intervals, pinpointing the precise aerobic threshold (a1 = 0.75) during endurance exertion.
