keybind presets

keybind presets lets you save and swap full control layouts in-game.

• A new controls entry Open Keybind Presets (unbound by default) opens the management screen. Bind it in Settings → Controls.
• The screen lists saved presets, shows the active one, and provides Save, Load, Rename (using the text field), and Delete actions.
• Saving captures every current key binding (including modded bindings) and writes them to config/keybindpresets.json. Loading applies the selected preset immediately and updates Minecraft’s options.
• Preset names are stored as entered; existing names are reused/overwritten on save, and rename blocks duplicates.

Known limitations / notes:

• The mod is client-focused; it loads harmlessly on servers but only the client UI does anything.
• Preset data is keyed by each binding’s translation key; if another mod removes or renames a binding, that entry will be ignored when loading.
