style: apply Prettier formatting to JS, JSON, and MD files

Apply consistent code formatting using Prettier to appropriate file types:
- Convert double quotes to single quotes in JS/MJS/JSON files
- Standardize indentation to 4 spaces across JS files
- Normalize spacing and line breaks with 120-char width
- Apply consistent trailing commas and semicolons
- Update package.json scripts to exclude YAML files from formatting
- Format ~500 JS/JSON/MD files while preserving YAML formatting
