Expand description

Saved user register frame from SYSCALL entry.

This struct matches the exact push order in syscall_entry assembly. After all pushes, RSP points to this layout (lowest address = first field). The struct is used by fork_process() to capture the live register state of the parent at the moment of the fork() syscall, so the child gets a copy of the parent’s actual CPU registers rather than the stale ThreadContext from process creation time.
