// buildCTE constructs a Common Table Expression (CTE) query in SQL for traversing
// a hierarchical structure of spaces and retrieving relevant registry IDs.
//
// Parameters:
// - parentID (int64): The starting space ID for the hierarchy traversal.
//
// Returns:
// - A formatted SQL string representing the CTE.
//
// Explanation:
// 1. The CTE is recursive and consists of two parts:
//    - Base case: Selects the initial node (space) with the given space_id (`parentID`).
//      It initializes the recursion level and tracks the path of visited nodes.
//    - Recursive step: Traverses the hierarchy upwards by joining the parent ID of
//      the current level with the space ID of the next level.
//      It ensures nodes are not revisited (`NOT s.space_id = ANY(sh.path)`), the recursion
//      doesn't exceed a depth of 10 (`sh.recursion_level < 10`), and parent IDs are valid.
//
// 2. Once the hierarchy is built, a second CTE (`registry_hierarchy_u`) selects unique
//    registry IDs from the `registries` table where `registry_parent_id` matches any
//    `space_id` from the hierarchical result.
//
// 3. The function uses `fmt.Sprintf` to inject the `parentID` into the SQL query template
//    before returning the final query string.
