THEN Move exact version pins out of pyproject.toml into a separate constraints file (e.g., constraints.txt) used only for Docker builds or lockfiles. Restore range-based dependency specs (e.g., pydantic>=2.5,<3) in pyproject.toml to express compatibility without locking environments.

# Instead of pyproject.toml with exact pins:
# [project]
# dependencies = ["aiohttp==3.13.5", "click==8.1.8"]

# Use a constraints.txt for Docker:
# constraints.txt:
# aiohttp==3.13.5
# click==8.1.8

# pyproject.toml with ranges:
# [project]
# dependencies = ["aiohttp>=3.10", "click>=8"]
