Replace Aight?

Build me a local-first iPhone client for Codex, Claude Code, OpenClaw,
and Hermes. Requirements:

- Use Swift 6, SwiftUI, and iOS 18. Generate Xcode from a checked-in
  XcodeGen project.yml so `xcodegen && xcodebuild` works on a clean clone.
- Build the Node.js 22 TypeScript companion with Fastify and WebSockets. Expose
  start, resume, prompt, event, approval, interrupt, and capability operations;
  session listing is optional and capability-gated.
- Ship real adapters for all four. Disable unavailable agents at runtime; all
  adapters must compile and pass fixture tests without every agent installed.
- Codex: pin the CLI version, run `codex app-server generate-ts`, and supervise
  app-server over stdio using the generated v2 types.
- Claude Code: use `@anthropic-ai/claude-agent-sdk`, its session APIs,
  async-iterable input for interrupt(), and canUseTool for permissions.
- OpenClaw: use the official Gateway WebSocket client, pair once, request only
  read/write/approvals/questions scopes, and store its device token securely.
- Hermes: use /v1/runs and its event, approval, and stop endpoints; use
  session headers for continuity and discover features from /v1/capabilities.
- Keep backend models in the companion and expose one versioned protocol. The
  iOS app stores its wss:// endpoint and bridge bearer token in Keychain.
- Provide backend/session pickers, streamed Markdown and tool events, approval
  cards, Stop, capability-aware controls, and deny approvals on disconnect.
- Bind to 127.0.0.1 and compare the random `.env` token in constant time;
  expose it only through private Tailscale Serve HTTPS, and never enable Funnel.
- Add bounded reconnects and local completion notifications. No app accounts,
  cloud database, analytics, or telemetry; agent model-provider calls remain.
- Out of scope: hosted relay, voice, cross-backend groups, templates, community
  skills, themes, multi-device sync, and a macOS client.
- Test adapter fixtures plus denial, interruption, and reconnection. README:
  setup for all four, `.env.example`, Tailscale, signing, permissions, limits.
