The smoke named its sandbox from a fixed run id. Daytona names sandboxes
uniquely, so when a run of the test was interrupted after the create had
gone out — a killed process, a test budget that expired mid-create — the
leftover sandbox made every later run fail with "already exists" until
someone deleted it by hand.
The test now generates a run id per execution and checks the label the
provider returns against that id, so an interrupted run leaves at most a
stray sandbox to prune and never blocks the next one.
