Infinite Inventory

What went wrong

1. No transaction support — inserts wrote permanently and ignored TransactionContext. Pipe mods simulate/roll back transfers; without SnapshotJournal, those rollbacks void items on the pipe side while the bag never reliably kept them.
2. No empty insert slot — size() was just unique item count, so every slot looked full. insertStacking (used by many logistics mods) only fills matching or empty slots, so new item types were rejected after already being pulled from the source.

What was fixed

• Pedestal handler now extends SnapshotJournal and only marks dirty / syncs on root commit
• Always exposes one empty slot for new item types
• Direct insert(resource, amount) path for whole-handler transfers
• Stable slot ordering for extract
• addItem / removeItem no longer wipe the crafting grid on every transfer
