fix(gui): keep Claude Desktop role selects inside the Models card

[lidge-jun]

Summary

This fixes a P2 from lane R4's GUI audit of the Claude Desktop Models card. When a stored role choice goes unavailable and its route is long, the role select's trigger grows with the text <route> (unavailable):

• at 390px the trigger runs past the card, so its chevron and the "(unavailable)" status are clipped;
• at 768px the trigger pushes the label column down to nothing, so "Default model" and its description wrap one word per line.

Measured in the screenshots below (sandboxed render, same data):

	390px trigger / chevron right edge vs card edge	768px label column width	768px trigger right edge vs card edge
before	673 / 660 vs 372 (overflows)	0px	939 vs 722 (overflows)
after	355 / 342 vs 372	152px	705 vs 722

Changes, limited to gui/src/pages/ClaudeDesktop.tsx and gui/src/styles/claude-page.css:

• The role-row controls column is bounded (max-width: min(60%, 28rem) on wide layouts and the full row when stacked), and the label column keeps a 12rem basis.
• Inside the trigger the route truncates with an ellipsis, while the translated "(unavailable)" status and the chevron never shrink. The status text comes from the existing claudeDesktop.roles.unavailableOption template, split around the route, so every locale keeps its own word order and no locale keys were added.
• The trigger's title carries the full route and status for the truncated case.
• Available models and the dropdown list are unchanged apart from the same truncation rule.

after

Verification

• No local tests were run, per owner instruction. A regression case was added to the existing gui/tests/claude-desktop-role-card.test.tsx (unavailable stored default: route and translated status render as separate elements, the trigger tooltip carries the full text, and an available role has no tooltip) for hosted PR CI.
• Static checks run locally, all exit 0: bun run typecheck, bun run lint:gui (oxlint), the GUI i18n lint, and bun run build:gui.
• Rendering: a sandboxed proxy built from this branch's dev base, with HOME, OPENCODEX_HOME, CODEX_HOME, CODEX_SQLITE_HOME, and XDG_* under one mktemp -d root and resolved state paths checked before launch, on random free ports. The sandbox config stores two long, unavailable role defaults. Vite served gui/ against that proxy, and headless Chrome (throwaway profile) captured each width through DevTools device-metrics emulation, measuring the card, trigger, chevron, and label rects. The before images come from the same session with the change stashed. The user's proxy, service, and apps were not touched.
• Hosted PR CI at the exact head is the merge evidence; per coordinator steering this PR is not platform-sensitive, so no full-matrix dispatch was started.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed. (Layout fix only; no behaviour or copy change.)
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (None involved.)

Summary by CodeRabbit

• Bug Fixes
  • Unavailable routes in Claude Desktop role selectors now display clearly alongside their status, and the current choice—including unavailable routes—is available in a tooltip. Route names and translated status text appear separately, making each part easier to distinguish.
• Style
  • Role selector layouts adapt across screen sizes. Long route names are truncated with an ellipsis while status indicators remain visible; on narrow screens, controls and selectors expand to use the available width.

📝 Walkthrough

Walkthrough

Role selectors render unavailable stored routes separately from translated status text and provide tooltips for selected choices. Responsive styles constrain selector widths and truncate long route labels.

Changes

Claude Desktop role selectors

Layer / File(s)	Summary
Unavailable route labels and tooltips gui/src/pages/ClaudeDesktop.tsx, gui/tests/claude-desktop-role-card.test.tsx	Role options use structured labels to separate unavailable routes from translated status text. The selectors provide tooltips for selected choices. A mounted test checks the unavailable default route, its status text, and tooltip.
Responsive selector layout gui/src/styles/claude-page.css	Role labels and controls use flexible widths. Long trigger and option routes truncate while status text and the chevron do not shrink. At widths up to 760px, controls and triggers expand to full width.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 7d4e8

Long role routes remain usable through truncation and tooltips. The identified gap is additional coverage for an available selection, with no concrete user-visible failure established; no material merge blocker remains.

Keep the role selects within the available mobile width.

At a 280 CSS-pixel viewport, the mobile layout leaves 210px for each control. The inline minWidth: 240 on both Select components keeps their .custom-select wrappers 240px wide despite the new width: 100% rule, so each control can extend about 13px beyond the card. Use min(240px, 100%) to preserve the 240px minimum when space allows and fit narrower rows.

Suggested fix

-                style={{ minWidth: 240 }}
+                style={{ minWidth: "min(240px, 100%)" }}

Apply this to both role selects.

Test the selected available-route tooltip.

The Quick task selector starts unset, so its null-title assertion does not cover a selected available route. After selecting Opus Model 3, assert the trigger label and title. Update the unset-selector comment to match what the existing assertion checks.

Suggested test update

   await choose("Quick task model", "Opus Model 3");
+  const quick = combobox("Quick task model");
+  expect(quick.textContent).toContain("Opus Model 3");
+  expect(quick.getAttribute("title")).toBe("Opus Model 3");
   expect(container.querySelector(".claude-dirty")?.textContent).toBe("Unsaved changes");

-  // An available choice keeps a plain label and its own tooltip.
+  // The unset Quick task selector has no tooltip.
   expect(combobox("Quick task model").getAttribute("title")).toBeNull();
