Function cfm_keystore_enumerate 

#[unsafe(no_mangle)]
pub extern "C" fn cfm_keystore_enumerate(
    ks: *mut FFIKeystore,
    module_id: *const c_char,
    app_id: *const c_char,
    compartment: u32,
    out: *mut *mut FFIKeyIterator,
) -> u32

Enumerate entries in one compartment of one (module, app) scope.

compartment: 0 = public, 1 = private. The returned iterator holds a snapshot; mutating the keystore during iteration is safe.
