Gemini-native image models now call interactions.create. result.id is the interaction id, so a later call can pass previous_interaction_id and edit without resending the image. Imagen stays on generateImages. thinkingConfig.thinkingBudget is rejected.
Describe previous_interaction_id, store, and thinkingLevel for Gemini native images. Re-export ThinkingLevel from the package.

The 1.5s settle after disconnect finished the run before a slow CI reload could see it still running. The page then restored image-restored, and retries loaded that finished snapshot as success.

- Around line 142-143: Add a bounded failure path around the waitForDisconnect
and resultObserved flow so a disconnect before the mount-probe GET arrives
terminates the abandoned durable producer and clears its active-run marker.
Ensure resultObserved cannot remain pending indefinitely, allowing retries with
the same thread ID to start from idle.

Clear runs when the mount probe never arrives.
If a reload ends before the mount-probe GET reaches this route, the disconnect fallback releases only waitForDisconnect; resultObserved has no timeout or abort path. The durable producer outlives the closed POST socket, leaving the run active. In CI, a retry uses the same server and thread ID, so its mount probe sees the stale run and rejoins it instead of starting from idle. Add a bounded failure path that terminates the abandoned producer and clears its active marker.
