Introduces a build script to automate the deployment process to Neocities.
This script:
- Reads API key from a `.env` file.
- Builds the Hugo site.
- Uploads all files to Neocities, displaying a progress bar.
- Implements error handling and color-coded output for better visibility.
Also includes `.editorconfig` for consistent code formatting, updates `.gitignore` and removes the `PaperMod` submodule.
