Mobile Off-hand Controls: Dedicated "Lefty Mode" & Interaction Overhaul

Following the community movement for Bedrock off-hand parity, I am requesting a dedicated "Lefty Mode" toggle in the settings. This would allow for a professional control scheme that is currently missing for mobile players. For the New Touch Controls, the "Sword" button should act as the primary attack, while a triple-tap on a hotbar item should be the gesture to move that item into the off-hand slot. For D-Pad users, a dedicated off-hand button should be added to the HUD to allow for independent interaction without needing the triple-tap gesture. To manage items efficiently, players should be able to long-press the "Interact" icon or off-hand button to swap their held item into the off-hand slot. This would finally allow mobile players to place blocks while mining or use a shield while attacking without the current "crouch-to-block" limitation. Implementing these specific UI changes—tailored for both touch and D-pad users—would make Bedrock more inclusive and professional for the entire mobile community
