fix(cli): resolve spawn EFTYPE on Windows for kimi web and /web

[ForgottenR]

Related Issue

Resolve #892

Problem

On Windows, spawnDaemonChild tried to execute dist/main.mjs directly. Windows does not honor shebangs and .mjs is not a PE executable, so CreateProcessW returns ERROR_BAD_EXE_FORMAT, which Node reports as spawn EFTYPE.

This only happens when the CLI entry point resolves to the .mjs script. Windows users who installed via the official single-binary install script (PowerShell / Homebrew / SEA) were not affected because their process.execPath is already a native binary.

Affected on Windows

• npm install -g @moonshot-ai/kimi-code
• pnpm add -g @moonshot-ai/kimi-code
• Running from source / development: pnpm dev:cli, node dist/main.mjs, etc.

Not affected on Windows

• Official PowerShell install script (irm ... | iex)
• Homebrew install
• Any installation that uses the single SEA/native binary

What changed

Changed spawnDaemonChild to run the resolved program through process.execPath:

• If the resolved program is already process.execPath (SEA binary or an already-running daemon child), pass the original args unchanged.
• Otherwise, prepend the script path as the first argument.

This keeps Unix/macOS behavior unchanged while fixing Windows.

Checklist

• I have read the CONTRIBUTING document.
• I have linked a related issue, or explained the problem above.
• I have added tests that prove my feature works. (Existing spawnDaemonChild test still passes; no new test added.)
