Note

Low Risk
Low risk dependency change: adds a minimum version constraint for zipp in requirements.extra.txt to address a known vulnerability; only potential impact is dependency resolution/version compatibility.

Overview
Adds zipp>=3.19.1 to requirements.extra.txt (with a security note) to mitigate a reported vulnerability, and normalizes the embeddings==0.0.8 entry formatting.
