[Concept] Craftable Ships & Dynamic Ocean Weather

Hi Mojang Team! I propose a major Ocean update to give survival players a true sense of freedom and mobility.

- The Craftable Ship (Mobile HQ): Instead of building block-by-block, players could craft a large, navigable ship directly from a new "Shipyard" station. To perfectly match the Vanilla style, this ship would use the exact 3D models of the existing ocean shipwrecks. Once crafted, it spawns moored to your dock. It acts as a mobile base (with your beds and chests), allowing you to move your whole HQ anywhere on the map without getting lost.

- Dynamic Ocean Weather: The ocean biome needs real waves based on the weather. Clear weather means calm seas. Rain creates 1-block waves that make the ship sway. Thunderstorms trigger massive 2-3 block waves, creating epic survival challenges where you must steer carefully or keep your ship safely anchored.

- Java & Bedrock Parity (Centered Map): This feature must be identical on both versions. Inside the ship, a Map Table would let you place a map that automatically updates and stays centered on your ship's coordinates as you sail, ensuring console, mobile, and PC players never get lost.

With competitors like Hytale or Roblox, Minecraft needs a real "nomadic base" feature. Reusing shipwreck assets is the perfect, Vanilla-friendly way to do it!
