0.1.0

• First non-prerelease release. Identical in code to 0.1.0-alpha.14;
  the version graduates the 0.1.0-alpha series. The alpha label is retired
  because the condition it described no longer holds: every shipped store
  adapter now carries the full ISignalProtocolLocalStore contract with its
  graduation checklist running as continuous CI gates — the storage contract
  suites in real Chromium, Firefox, and WebKit, the backend-conformance kit
  on Hermes, and the interruption, storage-pressure, multi-tab, and soak
  suites. The 0.x caveat stands: public APIs and persisted formats may
  change before 1.0.
