What's Wrong?

What happened

Ran /ultrareview on master (7 files, 8024 insertions / 3081 deletions). The remote session exceeded the 30-minute cap and returned no output:

> Remote review failed: remote session exceeded 30 minutes

When I went to retry, the prompt showed "Free ultrareview 2 of 3" — the failed run had consumed one of my three free uses despite producing no review output.

## Expected
Failed remote sessions (timeouts, infrastructure errors, no output produced) should not count against the free quota. Quota should only decrement on successful completion.

## Actual
Quota decremented from 3 → 2 on a run that returned no findings.

## Repro

1. Run /ultrareview on a branch large enough to trigger the 30-minute timeout
2. Wait for the failure notification
3. Re-invoke /ultrareview — counter shows "2 of 3" instead of "1 of 3"

## Environment

• Claude Code CLI on Windows 11
• Branch: master, scope: 7 files changed, 8024+/3081-
• Failed session: session_01At4ncgihLyqaUh5YntF4pw

## Suggested fix
Refund quota automatically when the remote session terminates without producing review output (timeout, crash, cancel-before-start). Alternatively, surface a clear "this run will not count" message before the user re-invokes.

What Should Happen?

not be charged for failed sessions
