A pure move, the first slice of splitting the client lib into crates:
- horizon-command: the command/ module (Brigadier port, vanilla tree, argument types, selectors), as is.
- horizon-client-core: what command needs from the lib, with no other dependency inside it: text, lang, snbt,
nbt_path, component, scoreboard, bossbar, gamerules, block_entity_nbt, fastutil_order; plus items moved out of
lib modules that sit in the cycle, unchanged: ParticleType (particles.rs), the key display name (keybinds.rs),
SOUND_SOURCES (settings.rs), uuid_text/uuid_from_text (save.rs), Registries/RegistryIds and parse_identifier
(command/args.rs).
horizon-client re-exports every module and item under its old path (`horizon_client::text`,
`crate::command::Registries`, `particles::ParticleType`...), so no caller changes. Inside the moved files only
paths changed (`crate::snbt` -> `horizon_client_core::snbt` in command, `crate::command::args::parse_identifier`
-> `crate::identifier::parse_identifier`...), `sign_side` became pub, lang.rs includes the lang files from
horizon-client's assets, and gamerules' test that saves a Level moved to save.rs (it needs the client's save).
