v1.1.0

• The shipped DDL no longer hard-codes table names: migrations/*.sql use
  {{exposures_table}} / {{conversions_table}}, resolved by
  ClickHouseMigrationRunner (requires rasuvaeff/clickhouse-toolkit ^1.6,
  or rasuvaeff/yii3-clickhouse-toolkit ^1.1 when wired through params).
  Until now exposuresTable / conversionsTable repointed only the writer
  while the migration always created ab_exposures / ab_conversions — setting
  them produced a writer inserting into a table nothing had created.
• Existing installations are unaffected. The runner hashes the resolved SQL,
  and resolving the new files with the default names reproduces the old files
  byte for byte (verified: both sha1 values are unchanged), so no migration is
  reported as diverged.
• Renaming a table after the migration has been applied is reported as a
  divergence — the README says what to do about it.
