uipath-maestro-flowe2eeditootb

Prompt

Add a script node called "convertToCelsius" between getWeather and formatSummary that converts the temp from F to C. Return both values. Also update formatSummary to include the Celsius value in its summary string.

Do NOT run flow debug — just validate the flow.
Do NOT ask for approval, confirmation, or feedback. Do NOT pause between planning and implementation. Build the complete flow end-to-end in a single pass.
Before starting, load the uipath-maestro-flow skill. Read and follow its workflow steps exactly.

### Summary of changes

**File:** `BellevueWeather/BellevueWeather/BellevueWeather.flow`

#### New node — `convertToCelsius` (inserted between `getWeather` and `formatSummary`)
```javascript
const tempF = $vars.getWeather.output.body.current.temperature_2m;
const tempC = Math.round((tempF - 32) * 5 / 9 * 10) / 10;
return { temperatureF: tempF, temperatureC: tempC };
```
Returns both `temperatureF` and `temperatureC` (rounded to 1 decimal place).
