Add Shuffle Filter item as subclass of Create's List Filter

[Copilot]

This PR implements a new Shuffle Filter item that extends Create mod's List Filter functionality. The Shuffle Filter is a subclass of FilterItem from the Create mod, allowing it to work identically to the List Filter while being programmatically distinguishable for future custom behavior.

Implementation Details

New Item Class

Created ShuffleFilterItem in package com.agent772.createshufflefilter that extends com.simibubi.create.content.logistics.filter.FilterItem:

• Inherits all List Filter functionality including the same GUI and behavior
• Configured with FilterType.REGULAR to identify it as a variant of the default List Filter
• Can be detected via instanceof ShuffleFilterItem for future differentiation
• Configured with default stack size of 64 (normal stacking behavior)

Crafting Recipes

Added two shaped crafting recipe variants to allow flexibility in nugget placement:

Recipe 1: Iron Nugget + Any Wool + Brass Nugget (left to right)
Recipe 2: Brass Nugget + Any Wool + Iron Nugget (left to right)

Both recipes:

• Accept any color wool using the minecraft:wool tag
• Produce 1 Shuffle Filter
• Allow iron and brass nuggets on either side as specified

Dependencies

Added Create mod version 6.0.6-98 along with required dependencies (Ponder, Flywheel, Registrate) via official Create mod maven repositories (maven.createmod.net and maven.ithundxr.dev).

Package Structure

• Main mod class: com.agent772.createshufflefilter.CreateShuffleFilter
• Filter item class: com.agent772.createshufflefilter.ShuffleFilterItem
• Mod ID: createshufflefilter
• All example code removed, focusing solely on Shuffle Filter functionality

Item Assets

Added complete asset support for in-game rendering and functionality:

• Item Model (models/item/shuffle_filter.json): Standard generated item model
• Item Texture (textures/item/shuffle_filter.png): 16x16 placeholder texture with purple/blue design
• Localization (lang/en_us.json): Display name "Shuffle Filter"
• Documentation (ASSETS.md): Comprehensive guide for assets and customization

The item is fully functional in-game with proper rendering, GUI access (inherited from FilterItem), and can be obtained through the creative tab or crafting.

Files Changed

• Updated build.gradle with correct Create mod repositories and dependencies
• Updated gradle.properties with proper mod identification and Create mod version properties
• Created CreateShuffleFilter.java as the main mod class
• Created ShuffleFilterItem.java with FilterItem inheritance and FilterType.REGULAR
• Added item model, texture, and localization files for in-game rendering
• Created two recipe JSON files for crafting flexibility
• Added ASSETS.md documentation

The implementation follows NeoForge modding best practices and uses proper Create mod integration patterns.

Original prompt

Create a new Filter called Shuffle FIlter. It should be a sub class of the Create Mod List Filter, and work the same way, use the same gui and everything. Its Subclass will later be used to detect and trigger a different bahavior.
The Crafting receipt should be the following:
Iron nuget, any wool, brass nuget. (In a row and if the iron nuget is left or right shouldnt matter)

the changes and naming are all in the example files. Please either rename the files and folders or move it to new so it no longer uses the example thingis but represent the mod itself like 'com/agent772/createshufflefilter/'

Package structure has been refactored from com.example.examplemod to com.agent772.createshufflefilter. All example files removed and mod now uses proper naming throughout. (commit 1a971ad)

@copilot looks good so far, did you include a placeholder for the item asset / what it looks ingame and all other needed things so it can be spawned and the gui entered ingame?

Yes! Added all necessary assets in commit 1344cac:

Item Assets:

• ✅ Item model JSON (models/item/shuffle_filter.json) - Uses standard generated item parent
• ✅ Item texture (textures/item/shuffle_filter.png) - 16x16 placeholder PNG with purple/blue design
• ✅ Localization already included for item name

GUI Functionality:

• ✅ Inherited automatically from FilterItem - right-clicking the item opens Create's standard filter configuration screen
• ✅ FilterType.REGULAR set, so it behaves exactly like Create's List Filter
• ✅ All filter operations work out of the box

Spawning:

• ✅ Available in Creative tab "Create Shuffle Filter"
• ✅ Craftable with two recipe variants (iron/brass nuggets + wool)

Added ASSETS.md documentation explaining all resources. The placeholder texture can be customized to better match Create's art style if desired.
