Scene Hierarchy ET switcher + Create Sublayer via Save dialog

- Add edit-target layer combo at top of Scene Hierarchy panel (always visible when stage loaded — session, root, sublayers); routes through LayerManager::SetEditTarget so StageEditor ET checkboxes stay in sync - Replace custom Create Sublayer modal with native SaveFile dialog; LayerManager::CreateNewSublayer creates the file on disk, inserts it at the top of the sublayer stack, and activates it as edit target Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
