MomentPlatform

JVM side of the Moment companion: the java.time engine behind parse/format, plus the java.time interop surface. Everything here is a companion member, so call sites need no import: m.toInstant and both Conversions resolve from Moment's implicit scope, Moment(instant) and Moment(ldt) are plain companion calls. Moment stays at millisecond precision, so sub-millisecond Instant precision truncates.
