T-294: Frame0 mock for pane collapse toggles + scope to visual affordance

Add the wireframe (states A/B) for edge-anchored collapse toggles on the
center pane. Records that collapse logic already exists (sidebar.collapse /
context.collapse commands) so the ticket is scoped to the mouse affordance.

Scope of this ticket: set up a Frame0 mock to talk through the design before implementing.
Open questions to resolve in the mock:
- Affordance placement: footer/status-bar anchored (as the screenshot arrows suggest) vs. pane-edge chevron.
- Collapsed state: fully hidden vs. thin rail with a re-expand handle.
- Iconography (chevron direction) and hover/active states.
- Whether sidebar and context pane share one control pattern (parity) or differ.
- Keyboard/CLI parity (D-6): each collapse action needs a clide verb.
Deliverable: Frame0 wireframe(s) of collapsed + expanded states for both panes, reviewed before any code.
DESIGN DIRECTION (settled): anchor both toggles on the OUTER EDGES of the center (Claude conversation) pane — one on the left edge controlling the sidebar, one on the right edge controlling the context pane. The control stays fixed on the center-pane edge whether the adjacent pane is open or collapsed, so a single button both collapses an open pane and re-opens a collapsed one (chevron flips direction). This avoids needing a separate "re-expand" handle on the collapsed pane.

IMPLEMENTATION NOTE: the collapse logic already exists — no new toggle behaviour needed. Commands `sidebar.collapse` (ctrl+shift+1) and `context.collapse` (ctrl+shift+3) are registered in lib/builtin/default_layout/src/extension.dart, exposed in the command palette + menubar, and call arrangement.toggleCollapsed(Slots.sidebar|contextPanel), returning isCollapsed (D-051, D-054).
So this ticket is scoped to the VISUAL AFFORDANCE only:
- Add the two edge-anchored toggle buttons on the center (Claude) pane''s outer edges.
- On click, invoke the existing `sidebar.collapse` / `context.collapse` commands (do NOT reimplement collapse).
- Read arrangement.isCollapsed(...) to flip the chevron direction per state.
- D-6 CLI/keyboard parity is already satisfied by the existing commands; this adds the mouse affordance.
