hide member memory from Obsidian graph view

Add a graph-view search filter (-path:members -path:.base) so the
30+ journal/on-the-user/revisit nodes drop out of the visualization.
View-only — the files stay in the vault index, so council-members.base
keeps rendering the roster and search keeps finding them.
