bone_sse: fix ribbon emitter offsets (#18-19), teardown guard

Browse Source

Bug #18: Ribbon emitter track offsets completely wrong. Position was
entry+0x24, actual tracks from assembly (0x716402-0x716AA9):
  Track 1 (Vec3): gate=+0x1C, AnimData=+0x10, output=+0x00
  Track 2 (Vec3): gate=+0x38, AnimData=+0x2C, output=+0x30
  Track 3 (float): gate=+0x70, AnimData=+0x64, output=+0x80
  Track 4 (Vec3): gate=+0x54, AnimData=+0x48, output=+0x50

Bug #19: Track 4 output was +0xA0 (should be +0x50), and tracks 2/4
were float (should be Vec3). Wrong output offsets corrupted stack data,
causing bone_rt pointer to contain float bit patterns.

Teardown: hook World_HandleLogoutCleanup (0x491180) instead of
CleanupWorldAndEntities (0x66FC40). Fires at START of logout sequence
before any Lua callbacks trigger model processing on freed data.
Prologue: PUSH ESI/EDI, epilogue: POP EDI/ESI, JMP (tail call).

Also: added bone_sse_reference.zig as separate compilation unit for
A/B testing the proven-working version independently.
