imagine/krea capped polling at 4min and leonardo at 5min while the caller's genCtx budget is 8min, so slow-but-valid generations were killed early with 'generation timed out'. Now the poll deadline tracks ctx.Deadline() minus 60s download headroom (fallback to the old fixed cap if ctx has no deadline). chatgpt already ties its budget to the deadline (pollBudget) and runway/grok honor ctx, so no change needed there.
