The mod holding the main game's own scenes and story follows the <game>_game
naming rule; further parts stay <game>_<part>, reusable content is <theme>_pack.
A collection is no longer a file inside a mod: it is a package (folder or zip)
named after its id with collection.json, cover and optional locale/, shipped in
collections/ next to the mods or kept by the player in user://collections/.
Covers and texts come from the package; mods do not ship collections.
Mods are renamed by role (shell2d_base, menu_base, ui_base, live2d_base,
editor_tools, cthangover_story, cthangover_murakami, cthangover_party) and
every reference follows. Engine UI prefabs (dialog, answers, message, game
menu, inventory, map, skills) and their panel entries moved out of the story
mod into the subsystem mods; the card_novel and vn_starter_novel collections
are removed.
