Functions
int32_t	reusex::core::cloud_label_at (const std::vector< CloudReferenceNode > &clouds, size_t cloud_idx, size_t point_idx)
	Helper for leaf nodes: read the label for point_idx from cloud cloud_idx, returning -1 if the index is out of range.
auto	reusex::core::parse_filter_expression (const std::string &expression, ProjectDB &db) -> std::unique_ptr< FilterExpression >
	Parse filter expression and resolve label cloud references from ProjectDB.
auto	reusex::core::evaluate_filter (const FilterExpression &expr, size_t cloud_size) -> IndicesPtr
	Evaluate filter expression against all points, generate Indices.
