Plugin System

We now have an overview of traits, how to define them and how they work, now it's time to put that knowledge to use and build a plugin system using traits.

A plugin in this system is any type that implements a specific trait. Each plugin will perform a specific task, and the system should manage a collection of these plugins, executing them in sequence. You’ll also address advanced issues like object safety and resolving potential conflicts between overlapping trait implementations.

Your Task

Design and implement a plugin system using trait objects. You will:

Define a Plugin trait that includes methods for initialization and execution.
Create a PluginManager struct to manage plugins. It should:
- Dynamically load plugins implementing the Plugin trait.
- Allow adding and removing plugins.
- Execute all registered plugins in sequence.

Requirements

The Plugin trait should include the following methods:
- fn name(&self) -> &str; - Returns the name of the plugin.
- fn execute(&self); - Executes the plugin's functionality.
The PluginManager should:
- Have the following methods and associated functions:
  - new() -> Self - Creates a new PluginManager instance.
  - add_plugin - Adds a plugin to the list.
  - remove_plugin - Removes a plugin from the list.
  - execute_all - Executes all registered plugins.
If a duplicate plugin is added (with the same name), it should panic.

Make sure you make all relevant items public.

Hints

Dynamic Dispatch: Store plugins in a Vec<Box<dyn Plugin>> for dynamic dispatch.
Plugin Uniqueness: Use the name method to identify and ensure uniqueness among plugins.
