pub.dev rejected 'flutter_haptics' as too similar to the abandoned 'flutter_haptic' package (last update 4 years ago). Renaming to 'haptic_kit' which matches the workspace convention (unity_kit) and is free on pub.dev.

Identifier changes:

- Package name: flutter_haptics -> haptic_kit

- Import: package:haptic_kit/haptic_kit.dart

- Method channel: dev.erykkruk/haptic_kit

- Android package + plugin class: dev.erykkruk.haptic_kit.HapticKitPlugin

- iOS plugin class: HapticKitPlugin

- Dart channel class: HapticKitChannel

Version 0.1.2 (0.1.1 was tagged but never published).
