Fix: Lowered scriptable GC

[crashkonijn]

This pull request refactors how configuration lists are constructed in the AgentTypeScriptable and CapabilityConfigScriptable classes to improve clarity and efficiency. Instead of using LINQ's Select and SelectMany, the code now explicitly iterates through collections and builds the configuration lists step by step. This approach makes the logic clearer and easier to debug, especially for complex nested object creation.

Key changes include:

Refactoring of configuration aggregation:

• In AgentTypeScriptable, replaced LINQ aggregation with explicit loops to build lists of goals, actions, and sensors, improving readability and maintainability.
• In CapabilityConfigScriptable, replaced LINQ-based construction of actions, goals, and sensors with explicit loops and intermediate lists, allowing for clearer logic and easier debugging.

Code cleanup:

• Removed unused using System.Linq; directives from both AgentTypeScriptable.cs and CapabilityConfigScriptable.cs as LINQ is no longer used.

Should fix #359
