/**
 * Guard against silently accumulating skipped tests.
 *
 * Counts `it.skip` / `test.skip` / `describe.skip` / `xit` / `xdescribe`
 * markers in test files and fails when the count exceeds the budget in
 * skip-budget.json. Lowering the budget as skips are fixed is encouraged;
 * raising it requires editing skip-budget.json in the same PR, which makes
 * the change visible in review.
