Greptile Overview

Greptile Summary

This PR adds Stainless SDK configuration for generating TypeScript and Kotlin SDKs and performs several OpenAPI spec cleanups:

• Added .stainless/stainless.yml with comprehensive SDK generation config mapping all API resources, models, and methods
• Added .stainless/workspace.json to configure SDK output paths
• Introduced AllErrors union schema to consolidate all HTTP error types (400, 401, 403, 404, 409, 412, 424, 500, 501) for Stainless SDK error handling
• Consolidated duplicate GridError schema definitions by removing redundant declaration
• Fixed phoneNumber example in UltimateBeneficialOwner to include '+' prefix matching E.164 format
• Corrected internal accounts schema path from users/InternalAccount.yaml to customers/InternalAccount.yaml
• Updated error response reference from Error to GridError in customer DELETE endpoint
• Added lint exceptions for new AllErrors schema and quote required properties

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• All changes are well-structured configuration and schema cleanup work with no logic changes. The Stainless config follows standard patterns, schema fixes correct existing issues, and all error references are properly updated throughout the spec.
• No files require special attention
