…ources in derived QueryPlans
Run the analyzer control with `serialize_query_plan = 0` so shards plan the SQL text and apply policies on the underlying table. Keep the legacy regression cases under the CI-provided settings.

… recompute on 26.8 On master the `CLEAR COLUMN` recompute set was narrowed to the dependency closure of the cleared columns by an unrelated feature, which is what keeps `MATERIALIZED` columns reading an `EPHEMERAL` column out of it. 26.8 still recomputes every `MATERIALIZED` column, so the backported tests `05055_clear_column_ephemeral_materialized` and `05153_clear_column_stale_materialized_warning` failed with `NO_SUCH_COLUMN_IN_TABLE` / `UNKNOWN_IDENTIFIER` for the `EPHEMERAL` column. Keep the broad 26.8 recompute set and only leave out the columns that read an `EPHEMERAL` column, both from `clear_affected_materialized` and from the per-command dependency check, which analyzed their expressions without the `EPHEMERAL` columns and threw.
