Keep docked navigation sizes consistent in narrow windows (#8052)

* fix(app): unify layout and density breakpoints

Align md styles with the existing 600pt compact/wide boundary so
600-719pt tablet windows no longer mix wide layout with compact metrics.
Keep the 500pt composer threshold local to its measured content width.

Let Settings navigation shrink before its detail pane falls below the
existing 400pt target, while retaining the preferred 720pt split budget.

Validated workspace typecheck, lint, formatting, real Chromium resize
checks, Duo portrait and landscape, and existing sidebar geometry tests.

* test(app): cover consistent docked navigation and readable Settings

Compare narrow and wide navigation density and Settings detail space
through the real browser journey, including compact Settings after resize.
The regression fails with main's split layout and density boundaries.

Compact-first. The small case is designed; the large case adds chrome around it.
The list+detail pattern is canonical and reused across surfaces. The settings shell (`packages/app/src/screens/settings-screen.tsx`) and the projects screen (`packages/app/src/screens/projects-screen.tsx`) implement it identically:
Use `md: 600` for both the compact/wide layout boundary and responsive density, in logical points on native and CSS pixels on web. Do not add a separate density breakpoint. Measured content constraints remain independent: composer controls use `COMPACT_CONTENT_WIDTH` (500), so a narrow pane can keep compact controls inside a wide window.
The settings shell (`packages/app/src/screens/settings-screen.tsx`) and the projects screen (`packages/app/src/screens/projects-screen.tsx`) share the canonical list+detail navigation pattern:
- On compact: full-screen list with `<BackHeader>` at the top. Tapping a row pushes a full-screen detail with its own `<BackHeader>` that returns to the list.
- On desktop: a 320px sidebar on the left holds the list with `surfaceSidebar` background. The content pane on the right holds the selected detail with `<ScreenHeader>`, `<HeaderIconBadge>`, and `<ScreenTitle>`.
- On wide layouts: a sidebar on the left holds the list with `surfaceSidebar` background. The content pane on the right holds the selected detail with `<ScreenHeader>`, `<HeaderIconBadge>`, and `<ScreenTitle>`.
The branching is one `useIsCompactFormFactor()` check at the top of the screen component. The list and the detail are the same components in both layouts; only the framing changes.
The workspace screen (`packages/app/src/screens/workspace/workspace-screen.tsx`) follows a different but parallel rule: tabs collapse on compact, panes split on desktop. The sidebar (`packages/app/src/components/left-sidebar.tsx`) is overlaid on compact and pinned on desktop.
On a narrow desktop route, app navigation yields to the rendered content topology when the remaining width cannot preserve its center target: Settings keeps its 320px list + 400px detail split, and a workspace Explorer keeps its current visible width plus a 400px center pane. That is a topology decision at the app container, not a second compact breakpoint. Temporary width clamps are render-only; widening restores the user's saved sidebar widths.
On a narrow window using the wide layout, app navigation yields when the remaining width cannot accommodate the content topology. Settings prefers a 720px split (320px list + 400px detail); its list shrinks first to keep forms readable without reducing the detail below 400px. Explorer reserves at least 240px plus a 360px workspace. These are local space budgets, not compact breakpoints. The app sidebar shrinks from its preferred 320px toward a 200px minimum to leave a 400px center target; its preferred width fits at 720px. Temporary width clamps are render-only; widening restores the user's saved sidebar widths.
Electron window controls are top-corner obstructions, not a compact-layout condition. Rendered surfaces declare which top corners they physically occupy; only those corners receive clearance. Full-window overlays redeclare both corners. A focused split pane owns both corners; if focus restoration temporarily exposes the full split tree, the split boundary reserves one top strip instead of assigning a control rectangle to an arbitrarily narrow leaf. The 720px desktop breakpoint preserves the default 320px sidebar and target 400px center width when the Explorer is closed; it is product policy, not an obstruction gate.

Windows and Linux controls are fixed window chrome, outside scrolling header content. A tab rail that reaches them ends at their obstruction and shows the shared overflow fade. On macOS, the Explorer toggle occupies a fixed top-right window slot so opening and closing Explorer does not move the pointer target.
