Fix order-dependent ASOIAF test skipping data() load before exists() check

[Copilot]

The ASOIAF test at line 415 of test-kinship2_aligns.R checked exists("ASOIAF") before calling data("ASOIAF"), so the test would silently skip when run in isolation or out of order — only passing when an earlier test had already loaded the dataset into the environment.

Change

• tests/testthat/test-kinship2_aligns.R: Moved data("ASOIAF") to before the exists()/nrow() guard in the "classic option passes through kinship2_alignped stages with ASOIAF" test, matching the pattern already used by all other ASOIAF tests in the same file.

Before:

test_that("classic option passes through kinship2_alignped stages with ASOIAF", {
  skip_if_not_installed("quadprog")
  # skip if not the correct data version
  if (!exists("ASOIAF") || !is.data.frame(ASOIAF) || nrow(ASOIAF) != asoiaf_nrow) {
    skip("ASOIAF data not available, or not the correct version")
  }
  data("ASOIAF")  # too late — check already ran
  ...

After:

test_that("classic option passes through kinship2_alignped stages with ASOIAF", {
  skip_if_not_installed("quadprog")
  data("ASOIAF")
  # skip if not the correct data version
  if (!exists("ASOIAF") || !is.data.frame(ASOIAF) || nrow(ASOIAF) != asoiaf_nrow) {
    skip("ASOIAF data not available, or not the correct version")
  }
  ...
