Struct KernelVTable 

#[repr(C)]
pub struct KernelVTable {
    pub create: Option<unsafe extern "C" fn(*mut c_void) -> *mut c_void>,
    pub get_contract: Option<unsafe extern "C" fn(*mut c_void, *mut c_void)>,
    pub open: Option<unsafe extern "C" fn(*mut c_void, *mut c_void) -> i32>,
    pub process: Option<unsafe extern "C" fn(*mut c_void, *mut c_void) -> i32>,
    pub close: Option<unsafe extern "C" fn(*mut c_void, *mut c_void) -> i32>,
    pub destroy: Option<unsafe extern "C" fn(*mut c_void)>,
}

算子的函数指针表(布局与 include/flow.h 的 LMFlowKernelVTable 一致)。 ctx/contract 参数在 C 侧是 LMFlowContext*/LMFlowContract*,此处用 *mut c_void 以免模块间循环依赖;ffi 层负责转换。
