v5.11.0

Changed

• Faster queries and hydration, measured with the benchmarks of tests/Benchmark: a query no longer copies the shared
  identity map, so that its cost no longer grows with the entities known (5,000 known: 160 µs down to 25 µs); the
  query is exported and masked for the query events only when they have listeners; the reflection of the hydrated and
  tracked properties, of the value objects, of the DTOs and of the lazy ghosts is read once; a response is decoded
  once. Hydrating 1,000 rows takes about 10% less time.

Added

• The walkers extending AbstractGraphqlWalker format the arguments as DefaultGraphqlWalker did: a dialect overrides
  formatEnum() to print a backed enum as an enum literal, and omitsArgument() to leave out the arguments its API
  refuses.

Fixed

• Data API Builder fetches the page after any cursor, "0" included, rather than the first page again.
• A count or an aggregate missing from a response, or not a number, says so and names it, rather than
  expected array, got "array": InvalidGraphqlResponseException::expectedNumber().
• The queries sent together with GraphqlQuery::concurrently() share their entities through the identity map: the
  second no longer creates another instance of an entity the first hydrated.
