✨ New: choose whether the current note stays open when going up
Two separately bindable commands (#12):
- Navigate to parent page — replaces the current note with the parent
- if the current note is pinned, it is kept open instead
- if the parent is already open in another tab, that tab is focused and the current note is closed (no duplicate tab)
- otherwise it replaces the current note in place
- Navigate to parent page in new tab — keeps the current note open
- focuses the parent if it's already open, otherwise opens it in a new tab next to the current note
Already-open parents are matched by file path (no more same-name collisions), and sidebar/background tabs are revealed on focus.
