- README cluster.search example uses 'phabricator/' to match host
  default (was '/phabricator'; both work for index name but the
  host uses path verbatim for the base URI).
- Add VERIFICATION.md placeholder with the planned smoke-test matrix
  template; status notes v0.1.0 is pending IS-474.
- Engine reindex: replace 'if ($time)' falsy check with 'if ($time
  !== null)' so a Unix epoch timestamp (0) is not silently dropped.
