[Bug] Ultrareview agents terminate prematurely on large diffs, consuming quota without output

Bug Description
Ultrareview consumed 2 of 3 free runs but produced no output — both failed server-side. Both runs failed with: "Review failed: all review agents terminated before completing." Run 1: session_01E8x9z4FjT4Cqf3NQ9MtHvk (scope: 45 files, 6080 insertions) Run 2: session_01YCAzvi3vVbznKWP9a7Cj8S (scope: 46 files, 6427 insertions) Both launched via /ultrareview on branch master, ~15 minutes apart, same repo. No review findings were returned in either case. The free-run counter still incremented (1 of 3 -> 2 of 3), so I lost 2 of my 3 free runs to a server-side failure I had no control over. Requests: 1. Restore the 2 consumed free runs. 2. Failed runs (orchestrator error, zero findings returned) should not count against the free quota. Possibly relevant: the diff is fairly large (46 files / 6.4k lines). If that size is causing the agents to terminate, an explicit size limit or a clearer error would be better than a silent quota burn.
