Aertech mod notes

• Adds a lightweight mechanical + energy sandbox. Right-click the Crank to emit a short mechanical pulse to adjacent components. Dynamos listen for those pulses, convert them into stored energy, and automatically push energy to neighboring blocks that expose AerStorage (including other dynamos and the High Furnace).
• AerStorage provides capped storage and capped transfer; energy moves in 200-unit chunks each tick while space is available. Dynamos show their buffer in chat when used.
• High Furnace is a 2-block-tall iron column with a custom screen (ore input, fuel/energy slot, doubled output, cobblestone byproduct). Any smeltable item yields twice the normal output plus 1 cobblestone when the progress bar finishes. It burns standard furnace fuels or consumes incoming energy if no fuel is present. Place with two blocks of vertical space; either half can be clicked to open the UI.
• All blocks are available in the Redstone/Functional creative tabs. Block drops and inventories are preserved on break; the lower half handles the inventory for the High Furnace.
• Notes/limits: no survival recipes are included; the energy value is internal-only (no gauge item yet); the mechanical grid currently propagates to adjacent mechanical components without longer-range shafts.
