Javadoc Serialization Strategy & WireMarshaller

[peter-lawrey]

A housekeeping sweep across serialization-strategy infrastructure and the core marshaller

Area	Change	Rationale
API Docs	Re-wrote/expanded Javadoc for: • SerializationStrategy + the SerializationStrategies enum • ScalarStrategy • WireMarshaller, FieldAccess, and the “unexpected field” marshaller • SerializationStrategies nested wrappers (Array/PrimArray/Demarshallable).	* Clearer contracts and type expectations * Links to related types * Added bracket-type semantics * Marked deprecations & removal schedules
Internal comments & tidy-ups	• Added missing @return / @param docs • Removed outdated references (DeltaWire, legacy flags) • Consistent first-line summary sentences	Easier onboarding; IDE hovers are now useful.
