[DOC] High level architecture diagram

# Create High-Level Architecture Diagram for Industry Toolkit

**Description:**
A high-level architecture diagram is needed to visually represent the components and workflow of the Industry Toolkit. The diagram should illustrate the key components, including the toolkit’s API generation, service templates (Java, TypeScript, .NET), workflows (e.g., Step Functions), SDK generation, and deployment process via CDK.

### Diagram Requirements:
- Visual representation of the key components of the Industry Toolkit.
- Include support for API-first development, multi-language SDK generation, and deployment using AWS CDK.
- Represent the workflow orchestration using Step Functions (or similar) for handling multiple capabilities.
- Illustrate how the toolkit integrates with CI/CD pipelines.
- Clearly show developer interactions with the toolkit (e.g., CLI, UI).
- The diagram should be clean, easy to understand, and suitable for presentations or documentation.

### Acceptance Criteria:
- [ ] High-level architecture diagram is created.
- [ ] Diagram includes all key components of the Industry Toolkit (API generation, templates, workflows, etc.).
- [ ] Diagram is reviewed for clarity and accuracy.
- [ ] Diagram is included in the project documentation and presentation materials.

Start by locating the project's documentation and presentation materials, then review how the issue's named components—API generation, Java/TypeScript/.NET templates, Step Functions, SDK generation, AWS CDK, CI/CD, CLI, and UI—fit together. Done means a clear architecture diagram is created, reviewed for accuracy and clarity, and included in the documentation and presentation materials.
