feat(redesign): design-system tokens, 23 Vue components, game-aware shell + Fleet/Solo dashboard

Tokens ported 1:1 from the Claude Design bundle (colors/game-themes/type/spacing/elevation/motion/fonts) with the data-theme/data-game theming contract via useThemeGame (+ cc-skin-swap repaint guard). 23 design-system components reimplemented as Vue SFCs (core/forms/data/navigation/feedback/brand). DashboardLayout rebuilt as the game-aware shell (GameSwitcher, grouped nav with permission gating preserved, agent-health footer, topbar). DashboardView: Fleet + Solo with per-game GAME_FIELDS rows and the themed ECharts PlayersChart; Solo wired to the real server store, Fleet on representative data pending the multi-instance backend. All four game skins (Rust/Dune/Conan/Soulmask). vue-tsc + vite build green.
