Part of #15991

Enables NullAway for the javaagent-extension-api module and adds required @Nullable annotations.

Files changed:

  • build.gradle.kts — enable otel.nullaway-conventions
  • AgentDistributionConfig.java — @Nullable on @JsonProperty constructor params
  • SafeErasureMatcher.java — @Nullable on safeAsErasure return
  • SafeHasSuperTypeMatcher.java — @Nullable on safeGetSuperClass return, next field; throw NoSuchElementException in next() instead of returning null
  • Utils.java — null-check on e.getMessage() before string comparison

Depends on: no dependencies
