Add Recce Cloud CI/CD integration

[even-wei]

Summary

This PR adds Recce Cloud integration to the CI/CD pipeline for automated dbt model change reviews.

Changes

• Added recce-ci.yml - Downloads prod baseline, runs dbt, uploads PR artifacts
• Added recce-prod.yml - Uploads production baseline on merge to main

How it works

• On PRs: Downloads production baseline → runs dbt → uploads PR artifacts to Recce Cloud
• On merge to main: Runs dbt → uploads new production baseline

• SNOWFLAKE_ACCOUNT
• SNOWFLAKE_USER
• SNOWFLAKE_PASSWORD
