0.9.0

symfony/var-exporter stays at ^6.4 || ^7.0 in require-dev: Doctrine ORM 3 builds its lazy ghosts with the
var-exporter 6.4/7 API and refuses version 8 unless native lazy objects are enabled ("Symfony LazyGhost is not available").

Added

• IndexNowListener can be built over a change-handler closure and a sink instead of the facade:
  new IndexNowListener(fn() => $services->changes(), null, $staging, $logger, sink: fn(array $urls) => $services->kit()->collect($urls)).
  The change handler is then built on the first flush that has something to classify, so an adapter with a lazy graph
  (Adapter\Services) no longer builds submitter, client and transport just to register the listener. The facade
  constructor is unchanged and keeps working, $autoFlush included.

Changed

• IndexNowListener::__construct(): the first parameter is $source (IndexNowKit|Closure), formerly $indexNow.
  Positional calls are unchanged; a call passing it by name (indexNow:) renames the argument (the bundle did).
• The test harness configures a second host with its own key, so conformance scenario C04 (URLs of two hosts -> one
  POST per host under its own key) actually runs here instead of being skipped.
• composer ci:install:orm3dbal3: the ORM 3 + DBAL 3 combination is declared supported but was never installed
  anywhere (highest = ORM 3 + DBAL 4, lowest and dbal3 = ORM 2 + DBAL 3). It uses phpstan.dbal3.neon like every
  other DBAL 3 flavour — the config switches on the DBAL major, not the ORM one.
• Requires indexnowkit/core ^0.13.
