Containment Viewer

Shows a diff view of Feature containment if/else blocks in Windows kernel code.

Usage

1. Place cursor on or before an if statement containing Feature_*_IsEnabled() or Feature_*::IsEnabled().
2. Run Show Containment Diff from the command palette (Ctrl+Shift+Alt+D).
3. A diff editor opens showing the Enabled block vs Disabled block.

If the condition is negated (!Feature_*_IsEnabled()), the blocks are swapped so "Enabled" always means the feature-on path.
