## Description

Union type representing all valid provider tokens in the DI system.

A token uniquely identifies a provider in the dependency injection container.
Tokens can be strings, symbols, class constructors, or factory tokens with type inference.

### Usage

```typescript
// String token
const token1: TokenProvider = "MY_SERVICE";

// Symbol token
const token2: TokenProvider = Symbol.for("MY_SERVICE");

// Class token
const token3: TokenProvider = MyService;

// Factory token with inference
const token4 = inject<MyService>();
```
