feat!: rebuild EveFlow as a JARVIS-style voice HUD for Hermes Agent (v2.0.0)

Complete rewrite of the application:

- Toolchain: Electron 44, Vite 8, React 19, TypeScript 5.9, Zustand, Vitest;
  main process rewritten in TypeScript (electron/), typed IPC contract (shared/),
  sandboxed renderer with webSecurity on and an HTTP/SSE proxy in the main process.
- Voice: AudioWorklet microphone capture at 16 kHz with adaptive energy VAD and
  auto-stop, WAV encoder, OpenAI-compatible STT, TTS queue with sentence-level
  streaming, prefetch and Web Audio playback feeding an analyser; hands-free mode,
  global push-to-talk hotkey, system-voice fallback.
- Hermes: full API client (capabilities, health, models, skills, toolsets,
  sessions, jobs) with automatic transport selection: runs API (SSE lifecycle,
  approvals, steer, stop) > sessions stream > chat completions with local tools;
  tolerant event normalisation; webhook receiver hardened (secret, size limit).
- UI: JARVIS arc-reactor core on Canvas 2D reacting to the real audio signal,
  holographic HUD layout (transcript, core, Hermes ops panel with tools/crons/
  skills/sessions/link tabs, telemetry), settings drawer, approval modals,
  compact floating widget, four themes, tray icon and global shortcuts.
- Removed the 3D Eve robot, three.js and legacy assets; migrated 1.x settings.
