WIP: ActivitySystem, BuildTools, HighwayTools

Activity System

The implementation pattern involves breaking down complex problems into smaller, more manageable parts that can be solved individually using the divide-and-conquer approach. This approach simplifies the code and enables the system to handle the coordination between activities. Once an activity is implemented, it can be reused in different contexts. For instance, if an activity that stores items in a chest is implemented, it can be reused by other activities to achieve different outcomes like for instance a stash mover.

Aquire items in any sitution from shulkers, ender chest, stash or by crafting
Synced inventory transactions
Reach XP level to auto rename or enchant
Basically any complex action in Minecraft

The new pattern introduces a new build engine known as BuildTools, which addresses the challenge of building complex structures in a more general way than legacy HighwayTools.

BuildTools

Supports the placement of directional blocks, axis-aligned blocks, halves, and other special blocks.
Compatible with Schematica.
Uses 0day exploit to force player rotation related directional blocks in the desired direction.
Enables the placement of blocks on surfaces that do not provide sufficient support for manual placement.
Yes works with 2b
