maxConcurrentAgentRuns and maxModelCallsPerMinute were per-JVM, in memory.
Preflight now fails stale RUNNING runs (no heartbeat for maxRunSeconds
plus 60s) and counts RUNNING runs across all products; the per-minute
limit counts model-call steps in the last minute and waits instead of
failing. Runs record heartbeatAt (new column) on each model call. The
policy's maxConcurrentAgentRuns override is now honoured.
The count-then-start window remains racy; the ConditionalUpdateAction
claim from qqq#1178 (QQQ 4.1.0-RC.7) closes it in a follow-up.
