WHY IT NEEDS A POLICY

Why smartling_upload_context needs a policy

This tool creates new context resources in Smartling's system by accepting image or video files. It's a Write operation (reversible, creates/adds data) rather than Read (only retrieves) or Destructive (permanent deletion). The severity is low because uploading context assets has minimal blast radius - worst case, unnecessary files are stored, easily cleaned up.

From the tool's definition Tool uploads/creates context data via imageUrl, filePath, or fileContent parameters - a write operation that stores visual assets in the translation management system. Description explicitly uses 'Upload' indicating data creation.
