Default the notes list to 200px with a 160px minimum and hide it automatically only below 600px. Keep the detail toolbar toggle available to open a drawer, with dismissal and note-switching support. Restore reading positions after rich text content effects populate the record.
Include the existing document-table and file-tree scroll anchoring styles in this file-level commit. Validation: 143 related tests, Electron layout regression, typecheck and changed-file lint passed; repository lint is blocked by unrelated App.tsx changes.
Release note: The notes list takes less space and remains accessible through a drawer in narrow windows. Existing saved list widths are preserved.
