Inconsistent rolling window behavior in Tesseract

[davajm]

Describe the bug
A simple rolling window sum is giving us different results depending on if Tesseract is enabled or not.

To Reproduce

1. Define following model in Cube

cubes:
  - name: test_cube
    sql: |
      SELECT TIMESTAMP '2025-10-07 10:00:00' AS created_at, 1 AS val UNION ALL
      SELECT TIMESTAMP '2025-10-08 10:00:00' AS created_at, 2 AS val

    dimensions:
      - name: created_at
        sql: created_at
        type: time

    measures:
      - name: val
        type: sum
        sql: val
        rolling_window:
          trailing: unbounded

2. Fetch measurement for whatever date range as long as it excludes one of the timestamps. Example filtering on 2025-10-08

{
  "measures": [
    "test_cube.val"
  ],
  "timeDimensions": [
    {
      "dimension": "test_cube.created_at",
      "dateRange": [
        "2025-10-08",
        "2025-10-08"
      ]
    }
  ],
  "filters": []
}

3. Execute above with CUBEJS_TESSERACT_SQL_PLANNER set to false and then when set to true
4. Note that it returns 3 when Tesseract is disabled, but 2 when enabled.

Expected behavior
I would expect them to be the same. Personally, the behavior when Tesseract is disabled looks more correct and stops us from being able to enable it right now.
