feat: frontend perf and a11y pass, plus mod visuals, hero main menu, Simple Voice Chat and vanilla chat autocomplete

Frontend:
- replace the i18next stack with a small typed i18n module
- hero clouds removed, llms.txt, HUD widget ARIA fixes and tests

Mod:
- TargetESP constellation mode; tracker and colors extracted
- JumpCircles: 7 new shapes, shared animation and color pipeline
- KillEffect blood mode with Burst/Fountain/Ring/Spray styles
- main menu: menuLayout setting (orbs/hero) and hero screen
- Simple Voice Chat soft integration: VoiceChat module and HUD panel
- renderer/quick: static Draw facade with glass outline
- vanilla chat: Baritone-style autocomplete popup for the % command prefix
