Add browser-based unit tests for xiaozhi test modules

- Add browser-compatible test files (no npm required) - recorder.test.browser.js: 8 tests for microphone and HTTP detection - tools.test.browser.js: 5 tests for Live2D actions and error handling - Add test runner (test-runner.html) with built-in test framework - Add null safety checks in tools.js for DOM element access - Add documentation (English and Chinese versions) - README_TESTS.md / README_TESTS_CN.md: Complete test guide - QUICK_START_TEST.md / QUICK_START_TEST_CN.md: Quick start guides - Total: 13 unit tests covering microphone detection, HTTP detection, Live2D actions, and error handling
