This commit adds a comprehensive hot reload example that demonstrates how to use the rhai_system for dynamic template rendering with Tera. Key improvements include:
- Refactor the example to use external script files instead of hardcoded Rhai code
- Implement proper module imports using the BasePathModuleResolver approach
- Fix template rendering by using keyword arguments in Tera function calls
- Add support for hot reloading both main and utility scripts
- Remove unnecessary output file generation to keep the example clean
- Fix compatibility issues with Rhai functions (avoiding to_string with parameters)
This example showcases how changes to Rhai scripts are automatically detected and applied to rendered templates without restarting the application, providing a smooth development experience.
