Pull Request Overview

This PR adds a basic introductory example for using OpenRouter with @effect/ai and @effect/ai-openrouter, demonstrating fundamental Effect-TS patterns for AI interactions. The example was extracted from a wrapper repository and has been formatted according to the project's code style.

• Adds a new src/basic/example.ts file demonstrating Effect-TS patterns
• Includes three examples: simple text generation, stateful chat conversations, and streaming responses
• Follows existing code patterns with layer-based dependency injection and Effect.gen composition

The new basic example is not included in the package.json scripts. The current examples script only runs the prompt-caching examples. Consider updating the package.json to include this new basic example:

"scripts": {
  "examples": "bun run src/basic/example.ts && bun run src/prompt-caching/...",
  "typecheck": "tsc --noEmit"
}

Alternatively, if this is intentional, consider documenting how to run this example in the README or in a comment at the top of the file.
