## Detailed Description of the Pull Request / Additional comments

### Problem

Users reported that disabling the "Automatically activate on utility
startup" setting for CursorWrap does not work - the mouse hook always
starts automatically regardless of the setting value.

### Root Causes

1. **`dllmain.cpp` `enable()` method**: `StartMouseHook()` was always
called unconditionally, ignoring `m_autoActivate`.
2. **`MouseUtilsViewModel.cs` `IsCursorWrapEnabled` setter**: enabling
CursorWrap forced `AutoActivate = true`, overriding the user's
preference.
3. **Startup edge case**: the trigger event could remain signaled from a
previous session, immediately toggling CursorWrap on startup even when
AutoActivate is off.

### Solution

1. **`src/modules/MouseUtils/CursorWrap/dllmain.cpp`**: only start the
mouse hook if `m_autoActivate` is true.
2. **`src/settings-ui/Settings.UI/ViewModels/MouseUtilsViewModel.cs`**:
remove the line that forced `AutoActivate = true` when enabling
CursorWrap.
3. **`src/modules/MouseUtils/CursorWrap/dllmain.cpp`**: reset the
trigger event on enable to avoid immediate activation on startup.

### Pattern Reference

This fix follows the same pattern used by **MousePointerCrosshairs**
module which has a similar `AutoActivate` setting that works correctly.

## Validation Steps Performed

### Build

- `tools\build\build.ps1 -Platform x64 -Configuration Debug`

### Manual validation (contributor)

#### Test Case 1: AutoActivate = false (should NOT auto-start mouse
hook)

1. Open PowerToys Settings → Mouse Utilities → Cursor Wrap
2. Enable Cursor Wrap
3. **Disable** "Automatically activate on utility startup"
4. Close PowerToys completely (right-click tray icon → Exit)
5. Restart PowerToys
6. **Expected Result**: CursorWrap module is loaded but mouse hook is
NOT active - cursor does NOT wrap at screen edges
7. Press activation hotkey (default: `Win+Alt+U`)
8. **Expected Result**: Mouse hook activates, cursor now wraps at screen
edges
9. **Actual Result**: ✅ Works as expected

#### Test Case 2: AutoActivate = true (should auto-start mouse hook)

1. Open PowerToys Settings → Mouse Utilities → Cursor Wrap
2. Enable Cursor Wrap
3. **Enable** "Automatically activate on utility startup"
4. Close PowerToys completely
5. Restart PowerToys
6. **Expected Result**: Mouse hook is immediately active, cursor wraps
at screen edges without pressing hotkey
7. **Actual Result**: ✅ Works as expected

#### Test Case 3: Setting persistence after restart

1. Set AutoActivate = false, restart PowerToys
2. Open Settings and verify AutoActivate is still false
3. Set AutoActivate = true, restart PowerToys
4. Open Settings and verify AutoActivate is still true
5. **Actual Result**: ✅ Setting persists correctly

#### Test Case 4: Hotkey toggle works correctly

1. With AutoActivate = false, restart PowerToys
2. Press hotkey → cursor should start wrapping
3. Press hotkey again → cursor should stop wrapping
4. **Actual Result**: ✅ Hotkey toggle works correctly
