0.8.0

Changed

• Middleware\IndexNowConnection::rollBack() discards the staged URLs in a finally (DBAL 4 and 3): a driver that
  threw on rollback left them staged, and the next successful commit on the same connection submitted the URLs of the
  rolled-back transaction. On DBAL 3 a commit() returning false discards them too.
• IndexNowListener accumulates a flush that another listener triggers inside postFlush() into the outer one instead
  of resetting the outer flush's pending entities.
• Requires indexnowkit/core ^0.11.

Added

• tests/CoreConformanceTest: the C01–C20 kit against the graph the Doctrine wiring is built around, as the framework adapters run it.
