Registers a core StatementExecutionListener (QQQ 4.1.0-RC.13) that
aggregates statements per unit of work (route, scheduled job, process),
table, operation and fingerprint in bounded memory, detects repeated
statement shapes per unit, and flushes each window with one batched
insert per table from a daemon thread that never measures itself.
