- new junit test module
- 4 initial tests for attack, follow, and flee
- improved regex to support <behavior> or *behavior*
- improved message cleaning
- refactor of HTTP requests to remove some Minecraft and Fabric specific imports

- Large prompt refactor for system chat message

Adding client language into both prompts, so entities will attempt to speak in the player's language (if valid and possible).

Updating system-chat prompt to include new class, skills, and background attributes, removing age, and rearranging them to match the character creation prompt. Also adding "Current " in front of Health and Hunger attributes.

Small refactor to entity character sheet context, and prompt - insert each line separately, instead of the entire character sheet. Added entity_health as well.
