feat: 跨实例同步移植 WIP 检查点（第1轮+2a+2b+synced_servers）

从 Axolotl 移植跨实例同步子系统，当前进度：

- 第1轮：synced_options/files.rs + mod.rs 骨架，state 层补齐 SyncedOption/InstanceSyncedOptions/CanonicalValue/GameOptionKind 等

- 2a：game_options 的 api_types/options_file/catalog(10文件)

- 2b：game_options 除 resource_pack_options/local_settings_editor 外的全部（settings_editor/write_shared_settings/fullscreen/launch_overrides/instance_support/read_instance_changes/pack_updates/source_selection + locales/5文件）；State 补 synced_options_lock/game_locale_indexer/lock_synced_options

- synced_servers：6 文件全部搬入

- 35+20 处 sqlx::query! 宏改写为非宏 query+bind

已知未完成：synced_servers::operations 依赖 synced_options::instance_option_supported（属 orchestration，第5轮），当前编译不通。
