Melon Shader Cycler

Added
Launch-time keybind check: on client startup, the mod verifies if the shader cycle keybind matches the Oculus reload shader keybind and notifies the player in chat if they differ

Client tick event listener: added a ClientTickEvent handler to wait for the player instance to be ready before sending the keybind mismatch notification (to handle player not being immediately available on startup)

Improved
Notification logic: added a boolean flag notifiedOnLaunch to ensure the keybind mismatch warning message is sent only once per client session, preventing chat spam on launch

Maintained
Existing keybind registration and shader switching logic remain unchanged

Key press event still validates keybind synchronization before allowing shader switching
