javadoc: doclint=all,-missing so Lombok @builder value classes pass

Javadoc runs on raw source before Lombok's processor, so it cannot see the
constructor class-level @builder generates and emits a spurious "use of default
constructor, which does not provide a comment" (the doclint `missing` group) for
TrainingParameters. Drop only the `missing` group; reference/html/syntax/
accessibility stay fatal (failOnWarnings remains true), so a broken {@link} or
malformed HTML still fails the build. Keeps the value class pure @builder with
no hand-written all-args constructor.
