fix: resolve TooltipPositionDelegate collision with Flutter 3.41

[amrgetment]

Summary

Fixes a compile-time symbol collision introduced after upgrading to Flutter 3.41.x.

Problem

super_tooltip defines TooltipPositionDelegate, and Flutter now also exports a type with the same name through material.dart, causing ambiguous resolution in lib/src/super_tooltip.dart.

Change

• Update import to hide Flutter's conflicting symbol:
  • import 'package:flutter/material.dart' hide TooltipPositionDelegate;

Validation

• Ran: flutter analyze lib/src/super_tooltip.dart
• Result: no issues found

Closes #160

@bensonarafat aside from this issue, I this issue, I would recommend using Codex to add E2E and visual automation testing so you can close several issues without worrying about that AI fixes would break something
