Juha Skin

mod.conf — sfinv moved from depends to optional_depends, so the mod loads without errors in any game. init.lua: build_tab now takes a plain page number instead of a context table, so it can be shared between sfinv and the command menu without faking a context object. Added cmd_page table to track the current page per player for the command menu. Added show_cmd_form() — builds a full standalone formspec (formspec_version[4], size[7.8,5.4]) and shows it via minetest.show_formspec. Added minetest.register_on_player_receive_fields handler for juha_skin:cmd — handles pagination and skin selection for the command menu, refreshes the form after selecting a skin so the active highlight updates immediately. Added /juha_skin chat command — opens the skin selector directly, no inventory needed. The entire sfinv.register_page block is now wrapped in if HAS_SFINV then ... end — it only runs if sfinv is present. register_on_leaveplayer now also clears cmd_page[name] on disconnect. README.md — fully rewritten in English, updated dependency table to mark sfinv as optional, added ## Modes section describing both access methods (command and inventory tab), added ## Notes clarifying sfinv behavior, removed the Installation section.
