ci: temporarily disable fusion/redshift tests (Fusion sidecar SVV_COLUMNS bug)

Summary

Temporarily removes the fusion/redshift entry from the CI test matrix. Fusion's sidecar adapter cannot resolve source schemas via Redshift's SVV_COLUMNS, causing adapter.get_columns_in_relation() to return empty and 92 of 167 tests to fail with compilation errors.

This is a Fusion-side bug, not something fixable in elementary. Confirmed by testing two approaches that had no effect:

• Version pin to preview.119 — same 92 failures (the bug predates preview.120)
• static_analysis: off in dbt_project.yml — same 92 failures (the sidecar still returns empty)

Validated facts (from CI logs)

1. 83 warnings: dbt1014: Failed to download source schema ... No schema in SVV_COLUMNS for <database>.<schema>.<table> — tables DO exist (created by dbt seed immediately before dbt test).
2. Two downstream error types: dbt1501 (26×, Jinja column resolution fails) and dbt1308 (62×, SQL PREPARE fails because relation not found by sidecar).
3. Reproduced identically on preview.119 and preview.120.
4. Other adapters (Snowflake, BigQuery, Databricks) pass on the same codebase and Fusion version.

Related dbt-fusion issues

• #615 — stale source schema cache / "No column found" errors
• #747 — missing columns in output.parquet
• #1304 — [EPIC] seeds non-parsing issues
• #1316 — baseline mode produces empty CTE from adapter.get_columns_in_relation()

Review & Testing Checklist for Human

• Verify fusion tests for other warehouses (snowflake, bigquery, databricks_catalog) still pass — this PR only removes the redshift matrix entry; other fusion targets should be unaffected.
• File an upstream issue on dbt-labs/dbt-fusion describing the Redshift SVV_COLUMNS regression so the CI entry can be re-enabled once fixed. An issue template was provided in the Devin session.
• Re-enable fusion/redshift in the CI matrix once the upstream fix lands.

Notes

• Failed CI job on PR feat: make override_primary_test_model_id Fusion compatible #930 is what triggered this investigation.
• PR Fix breaking changes in recent dbt-fusion version #920 also noted fusion/redshift was failing at the time (for different reasons — table materialization errors).
