v0.18.0

Added

• Documents written through the sync path now carry blinded indexed entries:
  the sync bootstrap reads each hmac-bearing private collection's stored /meta
  (after declaring its blinded-index attributes) and installs the persisted
  index schema on that collection's document cipher
  (LocalStore.applyCollectionMeta), so app writes are findable by equality
  queries. The installed schema survives cipher rebuilds (epoch rotations).
  Documents sealed before the schema was installed remain unfindable until
  rewritten.
• WasRemoteStore.readCollectionMeta reads a collection's raw stored /meta
  value.

Changed

• Upgraded @interop/was-client to 0.36.0 (adds the applyMeta / build-time
  meta support on createEdvDocCipher that the above uses).
