Summary

• rename the Databricks direct-landing path from native to delta
• add a real Databricks bundle/deploy/run/smoke surface for the Delta path
• document and expose the Delta operator flow through just and readmes

What Changed

• rename platform/databricks/native -> platform/databricks/delta
• add platform/databricks/delta/databricks.yml
• add platform/databricks/delta/resources/convex_delta_extract.job.yml
• add scripts:
  • scripts/render-databricks-delta-bootstrap.sh
  • scripts/deploy-databricks-delta.sh
  • scripts/run-databricks-delta-job.sh
  • scripts/run-databricks-delta-smoke.sh
• add just commands:
  • databricks-delta-deploy
  • databricks-delta-run
  • databricks-delta-smoke
• update repo/docs naming from native to delta
• document that the bundle scripts default to the direct deployment engine

Why

This turns the Databricks Delta path from checked-in pieces into a usable operator surface:

• one bundle config
• one deploy command
• one run command
• one smoke command
