7.0.0-alpha.1

Jackson 3 (tools.jackson 3.1.5) client, spring-boot4 module on Spring Boot 4.1.1.

Built against org.conductoross:conductor-common:4.0.0-alpha.1, from conductor-oss/conductor branch feat/spring-boot-4-upgrade (server release v4.0.0-alpha.1). ObjectMapperProvider keeps signature and wire-format parity with that build, so conductor-common and conductor-client can share a classpath in either order.

Breaking: consumers on Jackson 2 must migrate to tools.jackson or stay on the 6.x client line.
