[BUG] [WINDOWS] JSON object parameters

What's Wrong?

When the model generates tool calls with JSON object parameters (e.g., Bash command + description as a JSON object), the VSCode extension rejects them with:

InputValidationError: required parameter command

The call works when a single string parameter is passed, but fails when the tool call uses structured JSON object parameters. This affects Bash, Write, Read, Agent, and other tools.

What Should Happen?

Let the claude read and write normally.
