Add AI-powered policy builder and testing environment

Related to #9

Implement an AI-powered policy builder and testing environment in the Permit CLI.

* **New Commands**:
  - Add `permit playground build` command for interactive policy creation with AI suggestions.
  - Add `permit playground test` command for real-time policy testing and evaluation logs.

* **Documentation**:
  - Update `README.md` to include new commands and their usage.
  - Describe the new AI-powered policy builder and testing environment features.

* **Dependencies**:
  - Update `package.json` to include dependencies for AI-powered features.
  - Add scripts for building and testing the new features.

* **Command Implementations**:
  - Create `source/commands/playground/build.tsx` to implement the `permit playground build` command.
  - Create `source/commands/playground/test.tsx` to implement the `permit playground test` command.

* **Command Index**:
  - Update `source/commands/index.tsx` to include entries for the new `permit playground build` and `permit playground test` commands.

+## AI-Powered Policy Builder and Testing Environment
+
+### Interactive Policy Builder
+
+The `permit playground build` command allows users to create policies through a step-by-step interface, with visual representation and prompts for input. The AI suggests policy structures and rules based on user context to streamline policy creation.
+
+### Testing Environment
+
+The `permit playground test` command enables users to test their policies in real-time by running scenarios to see access results and evaluation logs. This feature enhances usability, reduces the time needed for policy creation, and allows for thorough validation, ensuring more secure and effective authorization strategies.
