Difficulty Lock

Please add a Difficulty Lock option to Minecraft Bedrock Edition, similar to the feature available in Java Edition. Currently, Bedrock players can freely change the difficulty of a survival world at any time. This can reduce the sense of risk and tension because players always have the option to switch to Peaceful or an easier difficulty when they are in danger. A Difficulty Lock would allow players to permanently lock a world to a selected difficulty. This would be especially useful for long-term survival worlds and Realms where players want to maintain consistent survival rules. Ideally, it should work similarly to Java Edition: once the difficulty is locked, it cannot normally be changed again. This would be an optional feature, so players who want to freely change their difficulty could continue doing so.
