0.12.1

Ossie schema 0.2.0.dev0. Tested with dactopus-ossie-clickhouse 0.14.0,
dbt v2 (dbt-oss 2.0.11) and dbt v1 (dbt-core 1.11 with
dbt-clickhouse 1.10) on ClickHouse 26.9, the WooCommerce package also on
26.7.

Changed

• CI installs dactopus-ossie-clickhouse 0.14.0 from PyPI instead of 0.12.0 from
  git.
• The commerce model's instructions no longer tell an agent that a store
  missing from a result has a zero for a ratio or an average, such as the
  average order value or the refund rate: it has a zero count or sum there
  and no ratio or average.
