Add input validation for colony configuration parameters

[mulkymalikuldhrs]

Description

Colony configuration parameters (like agent count, resource limits, simulation ticks) may not be properly validated before use. Adding validation would prevent runtime errors and improve the developer experience.

What to do

• Identify all configuration parameters used in colony setup
• Add validation functions that check for valid ranges and types
• Return meaningful error messages for invalid configurations
• Add tests for the validation logic

Prerequisites

• Basic understanding of the project's configuration system
• Familiarity with input validation patterns
