fix: keep the notes list accessible in narrow workspaces

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.

+## 2026-10-03: Compact Notes List And Narrow Drawer
+
+The notes list now defaults to 200px with a 160px minimum. At workspace widths
+of 600px or more it can remain beside detail; below 600px the toolbar toggle
+opens the mounted list as an overlay drawer. Escape, outside click, the close
+button and note selection dismiss it. Existing desktop width preferences remain
+intact. Scroll restoration now runs after read-only content effects populate the
+record, fixing a failure exposed by the Electron layout regression.
+
+Validation: 143 workspace and list-window tests passed, along with the real
+Electron layout test covering native resizing, drawer geometry, Escape focus
+return and note switching. Typecheck and lint on changed code passed. Repository
+lint was blocked by concurrent App.tsx changes (max-lines error and a missing
+conversationStore hook dependency warning). No provider calls were made.
