Add a built-in Invite Friends system support for Java Edition

Description: Dear Minecraft developers, I would like to bring to your attention the difficulties players face when trying to play multiplayer and customize visuals in Minecraft: Java Edition. First, it is currently very difficult to invite friends from other cities or countries to join a world because of complex networking requirements. I have been trying to invite my friend from another country for over 3 months without success. I kindly request that you add a built-in "Invite to Game" feature and a friend search function to Java Edition, similar to the one in Bedrock Edition. Second, I would like to request native, built-in support for shaders. Ever since I first installed Java Edition, I have dreamed of using shaders, as they make the game look incredibly beautiful. However, setting them up is often too complicated for many players. Implementing a built-in shader feature would allow everyone to enjoy the game's visuals without needing complex installations. Thank you for considering these improvements to make Java Edition more accessible and enjoyable for everyone.
