Five fixes to how `SMSG_UPDATE_OBJECT` is applied, each against the client's code:
- An out-of-range block never releases the active player (0x465f39–0x465f45).
- A movement block for the unit we move, the player or a possessed unit, is dropped (0x4670a5–0x4670bb).
- A create spline reads its three final-facing fields independently, in the order point, GUID, angle (0x47f0bf, 0x47f0e8, 0x47f0f9), so a server that sets two no longer breaks the packet.
- A game object is placed by its create block's position over its position fields (0x5f7046), and a re-create re-poses units only (0x46638c).
- The leave-world sweep's comment names the destroy path alone.
Byte-exact fixtures for the spline; each change has a test that fails without it.

Absorbed into the octo fork. Our tree has no ui_script/sweep.rs (upstream added it after our last sync), and the only change to it here was a comment; the file is dropped rather than orphaned. The five packet fixes apply unchanged.
