feat(throwing): add Raptor & StoneSlith and their SA artifact claws

Port Raptor and StoneSlith from ServUO (stat-for-stat) so the throwing
artifacts RaptorClaw and StoneSlithClaw finally have a real OSI drop source.
Both creatures spawn automatically from the Raptor/StoneSlith entries that
already exist in Distribution/Data/Spawns/post-uoml/termur/TerMur.json, and
each drops its claw from OnDeath at the ServUO 0.5% rate (uncontrolled only).
StoneSlith keeps its GraspingClaw monster ability; both use BleedAttack.

Idiomatic ModernUO: default range perception (16) and fight range, derived
GetSpeeds, [SerializationGenerator(0)] codegen, collection-expression arrays.

Documented omissions vs ServUO (missing from ModernUO, flagged as TODO):
Raptor's friend-spawn timer + 25% AncientPotteryFragments drop; StoneSlith's
TailSwipe, DragonBlood, and SlithEye/TatteredAncientScroll/AncientPottery
drops; plus HideType.Horned/Spined and PackInstinct.Ostard.
