Function are_exclusive_operators 

pub fn are_exclusive_operators<T, V, O>(
    target: &SiteIndexNetwork<V, T::Index>,
    operators: &[&O],
) -> bool
where
    T: TensorLike,
    V: Clone + Hash + Eq + Ord + Send + Sync + Debug,
    O: Operator<T, V>,

Check if a set of operators are exclusive (non-overlapping) on the target network.

Operators are exclusive if:

1. Vertex-disjoint: No two operators share a node
2. Connected subtrees: Each operator’s nodes form a connected subtree
3. Path-exclusive: Paths between different operators don’t cross other operators

Arguments

• target - The target site index network (full space)
• operators - The operators to check

Returns

true if operators are exclusive, false otherwise.
