Continuous Electrodermal Activity (EDA/GSR) Tonic & Phasic Deconvolution Analyzer based on sympathetic sudomotor biophysics.

    C --> D[Peak Detection & Threshold Screening > 0.05 uS]

```

## Features
- **Zero PIP Dependencies**: Implemented strictly with Python Standard Library (`math`, `json`, `sys`, `typing`).
- **Tonic/Phasic Separation**: Isolates slow baseline drift from discrete sympathetic sweat bursts.
- **Cognitive Workload Indexing**: Quantifies autonomic arousal and acute stress events per minute.
- **Dual Architecture**: Native Python import and Model Context Protocol (MCP) JSON-RPC 2.0 stdio server.

## Quickstart
```bash
python example_usage.py
```
