### Fixes

- Providers: preserve non-OK `text/event-stream` response bodies so provider HTTP errors keep their JSON detail instead of collapsing to generic streaming failures. Fixes #78180.

- Chat commands: make `/model default` reset the session model override instead of treating it as a literal model name. Fixes #78182.

- Cron: make rejected `payload.model` errors show the configured `agents.defaults.models` allowlist instead of echoing the rejected model twice. Fixes #79058.

- Agents/subagents: retry parent wake announces when the announce-summary model run fails with fallback cooldown exhaustion instead of dropping the wake on the first transient provider overload. Refs #78581.
