Fix Playwright process hanging - add timeout to browser.close()

**Problem**: Playwright helper tests were hanging indefinitely during cleanup, never exiting naturally. Process required SIGTERM to terminate.

**Root Cause**: The browser.close() method in _stopBrowser() was hanging and never completing. This is a known Playwright issue where browser processes don't terminate cleanly in certain scenarios.

**Solution**: Added 5-second timeout to browser.close() using Promise.race(). If browser.close() doesn't complete within 5 seconds, we force cleanup by setting this.browser = null.

**Testing**: Created test_playwright_direct.js to isolate the issue. Verified that:
- Tests now complete cleanly without hanging
- Browser cleanup happens within timeout window
- Process exits naturally without force termination

**Impact**:
- Fixes all Playwright test timeouts in CI
- Fixes coverage plugin tests (they were timing out before coverage could be written)
- Resolves GitHub Actions workflow failures for Playwright tests
