Add Electron IPC transport and CLI smoke coverage

[luokerenx4]

Summary

This PR moves the desktop app path toward an Electron-native transport while keeping the browser/dev/Docker HTTP path intact.

• Add Electron app://openalice loading and a preload bridge for renderer-to-Alice IPC.
• Route workspace file APIs and PTY shell traffic over Electron IPC in app mode; keep HTTP/WS as the web fallback.
• Add a local CLI gateway over Unix socket / named pipe for Electron mode so alice* and traderhub shims do not require MCP or an exposed MCP port.
• Make the MCP server optional and disabled by default in desktop app mode, while preserving explicit opt-in.
• Add electron:smoke:pty coverage for renderer PTY attach and CLI socket manifest behavior.
• Remove OpenCode's old OpenAlice MCP env/config injection and strip stale launcher env from spawned agents.

Why

Desktop app mode should not be forced through the same localhost web server shape used by browser/dev/Docker deployments. This reduces default port exposure, avoids fragile localhost coupling for the app shell, and keeps UTA separate because that process is intentionally designed as a detachable trusted trading sidecar.

The OpenCode cleanup closes the last obvious MCP injection trace: OpenCode now relies on the same CLI shim/tool socket path as the other agents, and inherited stale MCP/tool env is scrubbed before spawning sessions.
