feat: add skip_optimize model config to opt out of post-materialization OPTIMIZE

CHANGELOG.md

@@ -3,6 +3,7 @@
 ### Features
 
 - Add catalogs.yml v2 support (requires `use_catalogs_v2: true` in dbt-core) ([1440](https://github.com/databricks/dbt-databricks/pull/1440))
+- Add `skip_optimize` model config to opt out of the post-materialization `OPTIMIZE` call without dropping `zorder` / `liquid_clustered_by` / `auto_liquid_cluster` from the table definition. Useful when `OPTIMIZE` is delegated to Predictive Optimization or scheduled out of band. Complements the existing run-wide `DATABRICKS_SKIP_OPTIMIZE` var by allowing project-, folder-, or model-level opt-out via standard dbt config inheritance ([#703](https://github.com/databricks/dbt-databricks/issues/703)).
