feat(client): quick-create regular and temporary notes from Home and Space screens

Add fast note-creation entry points alongside the existing space-sidebar
actions.

- Home: refactor new-note-button.tsx into a reusable inner CreateNoteButton
  (parametrized by `temporary`/label/icon, keeps the 0/1/many writable-space
  resolution and space-picker dropdown) and render two equal-width buttons via
  `Group grow` — a regular note and a temporary note (IconHourglass).
- Space overview: new SpaceCreateNoteButtons component with two buttons that
  create a regular/temporary note directly in the current space and open it,
  reusing useTreeMutation.handleCreate (optimistic sidebar-tree insert +
  navigation). Permission-gated to members who can manage pages; a local
  pending state shows a per-button spinner and disables both to prevent a
  double-create. Wired into space-home.tsx above the tabs.
- Reuse existing i18n keys (no new strings): "New note", "New temporary note",
  "Create in space".
- Docs: add a CHANGELOG [Unreleased] entry and a "Temporary notes" roadmap
  bullet to README.md and README.ru.md.

 ### Added
 
+- **Quick-create regular and temporary notes from the Home and Space screens.**
+  The Home screen now shows a second action next to "New note" that creates a
+  *temporary* note (one that auto-moves to Trash after the workspace lifetime),
+  resolving the target space the same way the regular button does — created
+  directly when you can write to a single space, or via a space picker when
+  several. Each space overview screen gains two buttons — "New note" and "New
+  temporary note" — that create the page directly in that space and open it,
+  mirroring the existing space-sidebar actions and shown only to members who can
+  manage pages.
 - **Interrupt the AI agent and send a queued message now.** A queued AI-chat
   message gains a "send now" action that interrupts the streaming turn and
   immediately sends that message, keeping the agent's partial output. The
