Input.start_joy_vibration() is a documented engine no-op on Godot's HTML5 export (never wired to the browser side). Controls.vibrate() wraps it: native platforms go straight through as before, web drives the browser's Gamepad Haptic Actuator API directly via JavaScriptBridge. Gamepad movement/ability input already worked on desktop browsers via the standard Web Gamepad API, so only vibration needed a fix.
