Fix docs-consistency test assumptions for current README set

[Copilot]

The build-and-test (20.x) Actions job failed because docs-consistency tests referenced README-EN.md (not present in repo) and expected a Chinese debug-logging phrase in README.md (now English). This PR aligns test expectations with the current documentation layout/content.

• Root-cause alignment in docs test inputs

  • Switched documentation file lists from README-EN.md to README-zh.md in tests/docs-consistency.test.ts.
  • This removes ENOENT failures during markdown consistency checks.

• Assertion update for README language

  • Updated the debug-logging default assertion to match the current README.md wording:
    • Debug log files are not written by default.
  • Preserved the debug: true presence check.

const publicDocs = [resolve(root, "README.md"), resolve(root, "README-zh.md"), ...markdownFiles(docsRoot)];

expect(readme).toContain("Debug log files are not written by default.");
