Feature Request: Add OpenAPI Definition to Commit

[marcramser]

To improve integration and automation possibilities, it would be great if Commit could generate a standardized OpenAPI (Swagger) definition, ideally exposed as /openapi.json.

Benefits:

• Enables SDK generation across multiple languages, making it easier to consume the API programmatically.
• Allows automatic request validation to catch errors earlier.
• Supports CI/CD integration for automated testing and deployment workflows.
• Facilitates integration with API gateways and external tools that expect OpenAPI specs.
• Helps integrate Frappe APIs with systems outside the Frappe ecosystem, where OpenAPI is the de facto standard.

Rationale:
While the current approach with documentation and Bruno files is helpful for manual testing and internal use, providing an OpenAPI specification would open the door to a wider ecosystem of automation and tooling, increasing interoperability and developer productivity.
