Subject: [PATCH] fix: pin pandas and numpy to prevent strict typing crashes

Pins pandas to <2.2.0 and numpy to <2.0.0 in package requirements.
Recent updates to these libraries introduced strict type enforcement
(e.g., preventing implicit upcasting), which causes LossySetitemError
and empty DataFrame AttributeErrors during standard pyAMARES workflows.
This temporary restriction restores immediate stability.
