v1.1.2

• Failed tracker auto-flushes now emit a PSR-3 warning with the tracker kind,
  buffered count, and write exception. Buffer-cap event loss emits a separate
  warning with the dropped count. The config-plugin passes the application's
  LoggerInterface to the middleware and both trackers.
• Correct the delivery contract: reaching autoFlushSize may perform a network
  call during trackExposure() / trackConversion(), and direct ClickHouse
  delivery is best effort. Document the required outer middleware position.
• Run the Integration suite against a live ClickHouse service in CI so schema,
  migration, and write/read regressions can no longer pass via a skipped suite.
