Fix requirements.txt - Remove stdlib modules and add version constraints

[moshesham]

Problem

The requirements.txt file contains Python standard library modules that should not be listed as dependencies:

• uuid (line 3)
• logging (line 4)

Additionally, dependencies lack version constraints which can lead to breaking changes and inconsistent behavior across environments.

Current State

pandas
pyyaml
uuid
logging

Expected State

pandas>=2.0.0,<3.0.0
pyyaml>=6.0,<7.0

Impact

• Confusing for new contributors
• May cause installation issues with some package managers
• Unpredictable behavior across different installations
• Potential security vulnerabilities from outdated packages

Tasks

• Remove uuid from requirements.txt
• Remove logging from requirements.txt
• Add version constraint to pandas (>=2.0.0,<3.0.0)
• Add version constraint to pyyaml (>=6.0,<7.0)
• Test installation with updated requirements
