chore: add Prettier configuration

Add Prettier configuration for consistent code formatting.

This configuration:
- Uses single quotes for strings
- Enforces semicolons
- Sets tab width to 2 spaces
- Uses ES5 trailing commas
- Sets a reasonable print width of 100 characters

Helps maintain consistent code style across the project.
