fix: directory rename operation not working correctly

[phmatray]

Issue

The DemonstrateVFS command has a TODO comment indicating that the rename directory functionality needs to be fixed.

Location: src/Atypical.VirtualFileSystem.DemoCli/Commands/DemonstrateVFS.cs

Expected Behavior

Directory rename operation should work as expected, similar to file rename.

Current Behavior

Rename directory functionality is not implemented or broken (marked with TODO).

Suggested Fix

Investigate the VFS rename directory implementation and ensure it handles:

• Directory path validation
• Conflict detection (name already exists)
• Proper tree structure updates
• Event notifications if applicable

Priority

Medium - functionality gap in demo application

✅ Fixed in PR #131

The issue was that the demo code was using the wrong method signature for RenameDirectory. The method takes (VFSDirectoryPath, string), not (VFSDirectoryPath, VFSDirectoryPath).

All tests pass on net10.0.
