*Description:*
On the read path, ensure that the data type of lookup set literals is 
compatible with the SI column’s declared type. Specifically:
 * Allow index lookup only when types matches

 * If incompatible:

 ** *Preferred behavior:* Fallback to full table scan (no index)

 ** *Alternative behavior:* Throw query error
*Label:* {{{}blocker{}}}, {{{}si{}}}, {{lookup-validation}}
