Pull Request Overview
This PR updates the treatment indicator logic to support target treatment arms other than 1, enabling more flexible treatment effect estimation for multi-arm experiments.
- Fixed treatment indicator logic in local treatment effects computation to correctly identify treatment/control groups
- Added type annotations for better code clarity and IDE support
- Improved vectorization in stratified distribution computation

The treatment indicator logic is incorrect. For computing control treatment propensity, it should use 1 - (control_treatment_arm == D) instead of 1 - (target_treatment_arm == D) to properly identify control group membership.

no, current logic should be correct
