Added

• Pipe Terminal — access all inventories connected to the pipe network from a single block. Supports searching, extracting, inserting, and crafting directly from network resources. Place next to any item pipe to connect.
• Tiered Barrels — Oak (27 slots), Copper (45), Iron (54), Gold (72), Diamond (90), Netherite (108, blast resistant). Upgradeable in-place with barrel upgrades that preserve contents.
• Waterlogged pipes — all pipes can now be placed underwater. Water flows correctly around pipe geometry.

Changed

• Pipe crafting recipes reworked — tier 2+ pipes now require the previous tier pipe as an ingredient (e.g. Improved Item Pipe = 4× Gold Ingots + Basic Item Pipe). More logical tier progression.
