R008: 用例声明格式不规范

To validate XTS test case JSDoc format, scan `.test.ets`, `.test.ts`, and `.test.js` files to check that comment blocks use the `/** ... */` structure and each line starts with `*`.

The correct format for `@tc.name` and `@tc.number` tags requires using the `@` modifier with whitespace separation, disallowing incorrect separators such as `:` before the tag values.

Check for empty lines between JSDoc and `it()` by scanning test files to verify the doc comment closing `*/` ends immediately before the `it('...')` declaration without unintended gaps.

Static analysis detects malformed JSDoc comments in `.test.ets` files by enforcing the `/** ... */` structure, per-line `*` prefix, and correct `@tc.*` tag formatting with whitespace separation.

Scanning test case documentation format violations is limited to files with extensions `.test.ets`, `.test.ts`, and `.test.js`, targeting only JSDoc blocks placed before `it('...')` declarations.

Your XTS test case JSDoc block triggers a format warning if it violates required rules like missing per-line `*` prefixes, incorrect `@tc.*` tag separators, or empty lines between `*/` and `it(`.
