QA: page-tree and graph e2e packs in CI, manuals updated (#114)

Two new CI-wired Playwright packs, each in its own shared pond so the
fixture ponds stay untouched:

- page-tree.spec.ts — create-as-child with the form hint, collapsible
  folder view (collapse state survives reload), label view grouping,
  the local view override vs the owner-set pond default (fresh context
  without localStorage sees the new default), the Move-to dialog with
  the own subtree disabled, promote vs subtree delete, and a restored
  orphan re-attaching at the root.
- graph.spec.ts — pond graph nodes/edges/legend, node click-through,
  the phantom-create flow (dashed node turns solid), the local panel
  with hop toggle and highlight ring, and the permission slice: a
  label-denied reader sees neither the hidden node nor its edge.

Both packs 3× flake-free locally. Manuals: user guide (page tree,
moving/deleting with subpages, knowledge graph + local graph), pond
admin guide (sidebar view default), features.md (knowledge graph
bullet) — with the docs/de mirrors updated (English authoritative).
