Edited sub-entry should be an ancestor of selected leaf entr

Error message

Edited sub-entry should be an ancestor of selected leaf entry

What it means

An assertion in project panel editing: the entry being edited (new or renamed) must be the selected leaf entry or one of its ancestors; a mismatch means the edit state and the tree selection diverged, usually a state-sync bug after folding or ancestor-tracking changes.

Solutions

1. Recompute edit_state from the current selection when the tree changes
2. Ensure ancestors map is updated whenever entries are folded/unfolded
3. Cancel any active edit when selection changes to an unrelated entry
