Prompt
Create a UiPath Flow project named "SubflowDemo" that takes a string input called "text" and reverses it. The string reversal logic should be encapsulated inside a subflow rather than done directly in the main flow. Return the reversed string as an output. 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.

**File:** `SubflowDemo/SubflowDemo/SubflowDemo.flow`
**What was built:**
| Layer | Details |
|---|---|
| **Main flow** | `start` (Manual Trigger) → `reverseSubflow` (Subflow) → `end` (End) |
| **Flow input** | `text` (string, `direction: in`, bound to start trigger) |
| **Flow output** | `reversedText` (string, `direction: out`) — mapped from `$vars.reverseSubflow.output.reversed` on the End no
