feat: Add complete requirements and installation scripts

- requirements.txt: Added all dependencies including PyTorch,
  torch-geometric, tensorboard for neural network training

- install.bat: One-click installation script that installs all
  dependencies with proper version constraints

- train_neural.bat: Training script that runs parametric neural
  network training on collected FEA data

Usage:
  1. Double-click install.bat to install dependencies
  2. Double-click train_neural.bat to train on bracket study
