Add Java features to bedrock

While I understand that Java and Bedrock Edition run on fundamentally different codebases with distinct architectural limitations, it is frustrating that key features remain inconsistent between the two versions. For instance, the unpredictability of Bedrock’s Redstone makes complex builds incredibly difficult, and fixing this core mechanic should be a major priority for unifying the player experience. Furthermore, Bedrock's off-hand slot is criminally underutilized; players should at least be able to fire fireworks directly from their left hand, especially since the item can already be placed in that slot.  The lack of feature parity is even more apparent with structural elements like the armor stand "mannequin," which never received full Java-equivalent functionality in Bedrock. Moving forward, Mojang should commit to true parity by ensuring that whenever a new feature is added, it is introduced to both Java and Bedrock simultaneously. This would bridge the gap between platforms and prevent Bedrock players from feeling left behind by exclusive mechanics.
