Failed to regenerate chat title.

Error analysis
The test creates an OpenAI provider/model config and immediately calls RegenerateChatTitle. The in-process AI Gateway pool had just logged provider_count=0; its asynchronous provider snapshot reload had not incorporated the newly created route before the title request arrived. The request therefore hit the generated provider path before that route existed and returned HTTP 500.
The test helper createAdditionalChatModelConfigWithModelConfig waits for the HTTP create operation, but it does not synchronize with the AI Gateway pool reload. Because PasteOnlyChat runs in parallel, timing determines whether the route is ready.
Root cause
Classification: flaky test / asynchronous AI Gateway route-registration race. This is not caused by the commit under test.
No WARNING: DATA RACE, panic, OOM, resource-exhaustion, or abnormal process-termination evidence was present. This was a non-race test job and the test process completed normally with two distinct assertion failures in the overall run.

TestRegenerateChatTitle/PasteOnlyChat, seedPasteOnlyTitleSourceMessage, and the paste-aware manual title path were introduced by 2ad5af5b54d9b371d9b7e9d17657fe2cec73d111 (fix(coderd): use pasted-text attachments as chat title input) by Michael Suchacz. Assigning to ibetitsmike as the test/function owner. The failing run author is unrelated.

Related but different failure mode: #1481 (TestRegenerateChatTitle/RegenerationFailure, status wait timeout).
Suggested fix direction
After creating/updating the AI provider and model config, wait until the in-process AI Gateway pool has reloaded the provider route before invoking title generation, or construct this test with a synchronously registered route/fake transport.
