List notes

Notes in the workspace vault. Each row carries its raw tags and a parallel display_tags array of {tag, label, kind}, where a project scope tag resolves to the project name and a run tag to the question that run asked (E2E5-08); every tag has a label, and kind separates a subject from a scope key (E2E6-12). display_title is the title to show (E2E6-07), and display_summary is the excerpt to show beside it — the stored summary with the source site’s own chrome removed, or null when it held nothing else (E2E14-01). summary itself is returned unchanged, because it is editable.
