Module productivity 

Productivity calculation utilities for work time analysis.

This module provides centralized productivity calculations that distinguish brief interruptions from full absences to give accurate productivity metrics.

Key Concepts

• Short Pauses: Brief interruptions below min_pause_duration
• Long Pauses: Full absences at or above min_pause_duration, plus any manual pauses the user recorded (protected records bypass the threshold)

Productivity Formula

Productivity = (Net Work Time / Available Work Time) * 100

Where:
- Available Work Time = Total Time - Long Pauses
- Net Work Time = Available Work Time - Short Pauses
