Beta Release V0.1.4

What's New

Speed-Dependent Braking Model

• Replaced constant desired deceleration (d_des = 0.2 m/s²) with a physics-based Karwatzki brake shoe friction model (mu(v) = 0.6*(v+100)/(5v+100), UIC standard)
• Per-vehicle braking force computation respecting each vehicle's braked weight ratio (locomotive=0.9, cargo=0.6, tender=0.7)
• Service braking factor (default 0.5) converts emergency maximum to normal service level
• Corrected brake pipe propagation speed from 343 m/s (free-air) to 250 m/s (measured freight value, Qiao 2018)

Blended Braking Fix

• Capped regenerative braking at motor rated power with low-speed fade below 15 km/h
• Only the recoverable dynamic braking portion is used for energy regeneration

GUI Fixes

• Fixed empty plots on hidden tabs (Define Trains Paths plot)
• Plots now replot correctly when switching tabs

Build System

• Build-type-based paths for KDReports and RabbitMQ-C on Linux
• Updated Windows DLL copy logic and search paths
