Subject: [PATCH] fix(kimi-code): resolve Windows EINVAL in dev.mjs and reduce
 thinking flush rate

- Add shell:true for Windows in dev.mjs to fix spawn EINVAL
- Suppress DEP0190 deprecation warning for dev script
- Increase STREAMING_UI_FLUSH_MS from 50ms to 200ms to prevent
  eye-straining flicker during thinking streaming
