Dropplings

# Dropplings v1.2.0

The first internal gameplay foundation update of Dropplings!

This update introduces the first systems required for future item collection mechanics.

## ✨ Added

### 🧬 Species Systems

- Expanded the Droppling architecture with reusable internal systems.
- Added the foundation for Droppling internal storage.

### 🎒 Droppling Inventory

- Added `DropplingInventory`.
- Dropplings can now have an internal item storage system.

Added inventory functionality:

- Store ItemStacks.
- Add items.
- Remove items.
- Check capacity.
- Retrieve stored contents.

### 🏗 Entity Architecture

- Added inventory support to `BaseDropplingEntity`.
- All future Droppling species will inherit the internal inventory system.

## 🔄 Improvements

- Improved separation between:
  - Species data.
  - Entity state.
  - Gameplay behavior.

- Prepared the architecture for future systems:
  - Item collection.
  - Object absorption.
  - Visible stored items.
  - Inventory drops.

- Inventory contents are protected through defensive copying to prevent external modification.

## 🛠 Fixes

- Improved internal code organization.
- Reduced future complexity by separating inventory storage from entity behavior.

## ⚠ Known Issues

- The inventory is currently empty and is not used by gameplay yet.
- Dropplings cannot collect objects yet.
- Inventory contents are not saved after world reloads.
- Objects inside the Droppling are not visible.

## 📌 Notes

Dropplings v1.2.0 continues the architectural development phase of the mod.

This update does not introduce visible gameplay changes, but establishes the internal storage system required for future Droppling behaviors.

Future updates will focus on:

- Detecting nearby objects.
- Evaluating item preferences.
- Collecting objects.
- Storing objects inside the Droppling.
- Displaying stored items.

Thank you for supporting Dropplings! 💚
