Greptile Summary

The PR promotes the .NET SDK to version 8.0.0 and updates its API contract for Appwrite’s 2.0.0 response format.

• Adds Cloudflare and Resend OAuth provider support and new project-key scopes.
• Adds transaction-aware document creation, asynchronous credential-rotation responses, and updated model fields.
• Renames the TablesDB cutover operation and refreshes documentation and examples.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete blocking or non-blocking defects identified in the changed code.

The service methods, request parameters, response converters, enum values, model mappings, release metadata, and documentation remain internally consistent with the updated SDK contract.
