Follow-up to the budget-exhaustion recovery fix. recompute_ready's new circuit-breaker guard resolved its effective limit from per-task max_retries -> DEFAULT_FAILURE_LIMIT, skipping the dispatcher's configured kanban.failure_limit. _record_task_failure resolves max_retries -> failure_limit(config) -> DEFAULT, so the two disagreed whenever an operator set kanban.failure_limit != 2: - config > 2: a task could get stuck at DEFAULT(2) before reaching its allowed retry count. - config < 2: a task the breaker already blocked could be auto-recovered back to ready, defeating the stricter limit. Thread the dispatcher's failure_limit through dispatch_once into recompute_ready so the guard and the breaker share one resolution order. Updated test_circuit_breaker_block_still_auto_promotes (it asserted a failures=5 block auto-recovers and resets the counter — that's the pre-#35072 behavior the loop fix removes); it now exercises a below-limit transient block, with the at-limit case covered in test_kanban_db.py. Added two tests for the config-tier and per-task override resolution.
