v5.6.0

Added

• Resolution meta now includes versionTime (the resolved entry's timestamp)
  and ttl (the spec's cache-lifetime parameter). ttl is typed on
  DIDLogEntry.parameters, carried forward across entries like watchers,
  and reported as a number of seconds; when the log never sets it (or sets it
  to null), the spec default of 3600 is reported. Ports upstream 79d37f1
  (plus its tests 7392e53, 751d647), with the type corrected from
  upstream's string coercion to the spec's unsigned integer.

Fixed

• Resolving a deactivated DID with a historical selector (versionId,
  versionTime, or versionNumber) now returns the historical document with
  deactivated: true in the meta. Deactivation is DID-global state, so it
  previously read false at historical versions. Ports upstream 708e67f.
