Fix new_task tool streaming issue

[roomote]

Problem

The new_task command was not streaming partial messages to the UI like other commands do. When the new_task command writes a lot of instructions to a subtask, the UI appears frozen with no content until all content shows up at once, rather than streaming incrementally.

Root Cause

The issue was in newTaskTool.ts where partial messages were using a message property that doesn't exist in the ClineSayTool interface. The webview expects messages to conform to this interface for proper streaming behavior.

Solution

• Changed the message property to content in partial messages to match the ClineSayTool interface
• This makes the partial message format consistent with the complete message format
• Now the webview can properly handle and stream partial updates

Testing

• ✅ All existing tests pass
• ✅ Type checking passes
• ✅ Linting passes
• ✅ The fix aligns with how other working tools like writeToFileTool structure their messages

Files Changed

• src/core/tools/newTaskTool.ts: Fixed partial message property name

This is a minimal, targeted fix that resolves the streaming issue without affecting any other functionality.
