Update alpaca names and add livestock guardian dogs

Correct alpaca names: Onyx (Onu), Flocon (Floco), and Sapphire (Sapphi)
with descriptions, ages, and herd roles. Add Anatolian Shepherd LGD
page covering duties, daily care, bloat prevention, and adolescent
play stage. Frame LGDs as gentle and approachable working dogs that
welcome guest socialization. Add prominent rule against uninvited
outside dogs with leash requirement for approved visiting dogs;
mirror in house rules.
