Update system-chat, remove syntax example, change USER/ASSISTANT to PLAYER/ENTITY, simplify FLEE and PROTECT behaviors.

Updated README.md with new video thumbnail, and simplified text, added spoiler to install instructions

- Added new LLM tests for UNFLEE
- Fixed certain behaviors from colliding with others (i.e. mutual exclusive ones)

- Fixed a **crash with FLEE** when non-path aware entities (i.e. Ghast) attempted to flee.

Release 1.0.7 (Protect behavior)

See merge request !10

Added `PlayerBaseGoal` class to allow **goals/behaviors** to **continue** after a player **respawns** / logs out / logs in. Fixed teleport issue to be closer to player position, and fixed a regression caused by teleport that stopped following entities that were too far away.

- New PROTECT behavior
- Native ATTACK abilities
- Improved FOLLOW (with teleportation)
- Improved FLEE (more random, more reliable)
