• Added support for GPT 5.5 and GPT 5.5 Pro via the OpenAI provider (#54828)
• agent: Fixed an issue where sessions would not immediately be cleaned up when archiving (#54775)

• Fixed agent threads appearing to be missing after upgrading to the parallel-agents sidebar. The thread-metadata migration was racing against the on-disk thread store's async reload and skipping itself on every launch. Upgrading to this build runs the migration successfully; previously-missing threads are surfaced either in the sidebar (5 most recent per project) or in the archive view. (#54751)
