Streamed context uploads and CLI SSH format fixes

Daytona 0.211.2 hardens sandbox context uploads and CLI build behavior, adds retry on stale connections in the TypeScript SDK, and stops resolving the API URL from .env files across the Python, Ruby, and TypeScript SDKs.

Fixes

CLI: enforce the documented SSH command format

CLI: fix build context archive path and COPY source resolution

Go SDK, Python SDK, Ruby SDK: stream context uploads as multipart

TypeScript SDK: retry requests on stale connections

Refactor

CLI: resolve toolbox proxy URL from the sandbox object

Breaking Changes

Python SDK, Ruby SDK, TypeScript SDK: do not resolve the API URL from .env. DAYTONA_API_URL and DAYTONA_SERVER_URL set in .env or .env.local are ignored; set them in the process environment or pass api_url to the constructor.
