[Bug]: React #185 renderer crash recurs in ProviderModelPicker chunk on Alpha 0.0.40

Before submitting

• I searched existing issues and did not find an open duplicate.
• I included the available details needed to investigate the crash.

Area

apps/desktop

Steps to reproduce

1. Use the T3 Code Alpha desktop app version 0.0.40.
2. Open or use an existing thread.
3. The renderer can crash to the T3 Code crash screen.

The exact interaction immediately preceding the crash was not captured, so this is not yet a deterministic reproduction. The environment/thread path from the crash screen is intentionally omitted because it contains private identifiers.

Expected behavior

The thread should remain usable and the desktop renderer should not crash.

Actual behavior

The renderer crashes with React error #185 (Maximum update depth exceeded). The later frames are in the ProviderModelPicker production chunk, though the minified stack alone does not prove that component is the root cause.

This may be a recurrence or a distinct path related to #9481. Its fix in #9482 is included in v0.0.40.

Impact

Major degradation or frequent failure

Version or commit

T3 Code (Alpha) 0.0.40

Environment

T3 Code desktop app. OS and provider/model were not captured.

Screenshots, recordings, or supporting files

None. No private logs or screenshots are attached.

Workaround

Unknown.

Start in apps/desktop and trace the source corresponding to the ProviderModelPicker production chunk. Reproduce the crash in a non-minified development environment, then compare the behavior and fix described in #9481 and #9482. Done means the thread remains usable without React error #185 or a renderer crash.
