Halyx 1.0.2

A patch release. Upgrade by changing the halyx-bom version to 1.0.2; there are no API changes.

Fixes

• JSON cache codec on Spring Boot 4 (#9): with
  halyx.cache-manager.codec=json and Jackson 2 on the classpath too, as halyx-azure brings it, the codec used
  Jackson 2 without Java date/time support, so caching a value with an Instant failed. Jackson 3 is now always
  preferred when present.
• Cancelling a reactive call (#12): cancelling a ReactiveHalyx
  call that had started, by timeout() for example, interrupted its thread on the default virtual-thread scheduler
  and on boundedElastic, which could abort a blocking SDK call partway through. A started call now runs to
  completion and its result is dropped, as documented; one cancelled before it starts never runs. The docs now also
  say that calls on the non-blocking path are cancelled with the subscription, and the driver may abort the request.

Samples

• Plain Java quickstart (#2): halyx-samples/plain-java-quickstart
  object storage, messaging and parameters without Spring, on the in-memory provider by default or on a cloud through
  system properties; linked from the README and Getting started. Contributed in
  #8.

Thanks @omisha123 for the plain Java quickstart (#8)!
