bug: Dialog default value displays message instead of defaultValue

[mithun50]

Description of the bug

Bug Description

In McpResponse.ts, the dialog information display shows
dialog.message() twice instead of showing the actual
default value.

Location

File: src/McpResponse.ts
Line: 196

Current Behavior

${dialog.type()}: ${dialog.message()} (default value:
${dialog.message()})

This displays the dialog message as both the message AND the
 default value, which is incorrect.

Expected Behavior

${dialog.type()}: ${dialog.message()} (default value:
${dialog.defaultValue()})

Should use dialog.defaultValue() to display the actual
default value of the dialog.

Example

Current output:
prompt: Enter your name (default value: Enter your name)

Expected output:
prompt: Enter your name (default value: John Doe)

Impact

• Severity: Minor
• User Impact: Confusing UX - users see incorrect
  information about dialog default values
• Functionality: Does not break functionality, but displays
  misleading information
