Summary

• Preserve names returned by the app server when building sidebar thread summaries.
• Keep explicit local renames as the highest-priority display name.
• Retain the existing message-preview and numbered-agent fallbacks for unnamed threads.
• Accept title as a compatibility fallback when name is unavailable.

Why

Imported or externally named chats can already have a useful server-provided name. Replacing it with the first-message preview makes those chats harder to identify and can make the sidebar disagree with the source application.

Testing

• npm run typecheck
• vitest run src/features/threads/utils/threadSummary.test.ts — 4 tests passed
• vitest run — 139 test files and 1,003 tests passed

Ignore UUID placeholder names when building summaries

When the server-provided name is the thread's UUID and no local rename exists, this now chooses the UUID over a useful message preview. onThreadNameUpdated already rejects this exact placeholder in useThreadTurnEvents.ts:172–178, with a corresponding regression test, but list refreshes now bypass that safeguard and replace readable sidebar labels with IDs. Apply the same placeholder check before preferring the server name so these sessions retain the preview or numbered-agent fallback.
