Explorer's Ender Chest

A big quality-of-life and polish update.

Added

• Config screen — via ModMenu (needs Cloth Config; both optional). Toggle the unlock requirement, "remember open" state, recipe-book auto-close, sounds, and animation speed. Also editable at config/enderpocket.json.
• Open from anywhere — bind a key in Controls and press it in-world to open your inventory with the panel already out.
• Sounds — ender chest open/close sounds when you toggle the panel.
• Slide-out animation — the panel now glides out from behind the inventory instead of popping in.
• Resource pack support — the panel auto-themes from your pack's own chest texture, and the button is the vanilla ender chest item so it matches your pack too. Packs can further override positions (gui_layout.json) and supply a dedicated panel texture. See the README.

Changed

• The panel now always opens at full size. When the screen is too narrow, the inventory slides left to make room instead of anything shrinking.
• With active potion effects, the panel positions itself below the effect list so nothing overlaps.
• The button now sits inside the inventory's button row when there's space, and moves to the top-right corner when it's occupied (e.g. by other mods).
• Opening the panel auto-closes the recipe book for that inventory session. Re-open the book and it stays — the layout gently scales to fit everything.

Fixed

• Items no longer briefly missing for a few frames when the panel opens.
• The panel no longer peeks out from behind the inventory with some resource packs.
• Recipe-book auto-close no longer stops working for the rest of the session after you re-open the book once.
