Restrict Agent name to string only, raise TypeError for int/boolean

[AsnaSiddiqui]

Description

Restricted the Agent name parameter to only accept str types, raising a TypeError for int or boolean inputs. Changes:

• Updated agent.py to enforce str type using __post_init__ and raise TypeError for invalid types.
• Updated tests in test_agent_name.py to verify str acceptance and TypeError for int and bool inputs.

Testing

• Run pytest tests/test_agent_name.py successfully (1 passed, 2 failed with TypeError).

Checklist

• Code changes
• Tests added
