🧪 Testing

Auto-stack:

• There is a sort button on Exosuit, Starship, Freighter and Chest (0-9), clicking on it will move all matching items from the current inventory to the target inventory.
• Exosuit and Starship Cargo have a context menu, where you can also auto-stack only the slot you right-clicked.
• You can pin a slot from the context menu. Pinned slots are ignored by auto-stack.
• If you use the single-slot auto-stack action on a pinned slot, the action is blocked.
• If the destination stack becomes full, the extra items go to another free slot in the same destination when possible.
• If there is no valid free slot, the remaining items stay in Exosuit Cargo.
• Pinned slots are persisted locally-only via AppConfig.

Sort:

• There is a sort button on Exosuit, Starship, Freighter and Chest (0-9), just click on it to sort the inventory.
• Sort does not ignore pinned slots.

💬 Notes

The code was mostly generated by LLM and I revised/tested. Everything is working as expected, tested on my own savegame.
