UR-Nexus 1.57.5

• Fixed the release gate failing on repoEditImports. The gate runs
  bun test --timeout 120000, but a per-test budget silently overrides that
  global, and this test declared 15s while its body — which builds a
  TypeScript program to resolve imports — takes about 21s on a 2-core CI
  runner. Every assertion passed; the release went red on timing alone.
• Added a guard so this cannot recur: a test now fails if any test file
  declares a per-test budget below 60s. Both budgets that broke CI (15s and
  20s) are flagged by it; ordinary call arguments are not.
