Give scp939 a lying death pose instead of a crouch

[iwaterheater]

What

When an scp939 dies it stays hunched on its legs in a head-down crouch instead of looking dead — it reads as if it's still crouching/prowling. This gives it a proper lying death pose.

Cause

scp939 uses its own 939_Die → 939_Dead clips (not the shared Death01_Rig). Both end in a crouched, head-down pose — the body never actually settles onto the ground, and 939_Die passes through a lunge-like shape that looks like an attack on the way there.

Fix

• data-src/monsters.csv — point scp939's animDie/animDead at 939_Sleeping, a curled lying pose already present in scp939.glb, so the corpse lies on the ground and reads as dead. Reusing it for animDie too skips the lunge-through frame.
• client/.../Monster.svelte — lengthen the death cross-fade 0.2s → 1.0s so the body settles onto the ground smoothly instead of snapping into the pose. Heads up: this affects every monster's death transition, not only scp939 — glad to scope it per-monster (a deathFadeSeconds def field) if you'd prefer.

Verification

• Rendered scp939's candidate death poses in an isolated three.js harness: 939_Sleeping is the only lying/curled pose — 939_Die, 939_Dead and 939_FullStagger are all crouches (see image above).
• Tested in-game (local server): the monster now settles onto the ground in the lying pose on death.
• prettier --check clean on the changed Monster.svelte; only these two files change.

Merged — thanks! I took you up on the per-monster scoping suggestion in a follow-up commit (9e85be4): monsters.csv now has a deathFadeSeconds column (scp939 = 1.0, default 0.2), so the slow settle applies only to scp939 while the other monsters keep their original 0.2s death fade.
