Walkthrough

The pull request migrates the test suite from Mocha/CommonJS to Playwright/TypeScript. tests/package.json swaps mocha for @playwright/test and typescript; a new tests/tsconfig.json and tests/playwright.config.ts configure the TypeScript compiler and Playwright runner. A new tests/global-setup.ts handles simulator discovery via xcrun simctl, launches the XCUITest runner bundle with the JSON-RPC listen port injected, and polls /health before tests start. tests/rpc.test.js is removed and replaced by tests/rpc.test.ts; tests/mjpeg.test.ts is converted from Mocha to Playwright. scripts/test-coverage.sh is rewritten to build an instrumented runner via xcodebuild build-for-testing, install it on the simulator, run Playwright tests with coverage env vars, and merge .profraw files via llvm-profdata. The Makefile coverage-html target switches from find-based profdata discovery to a fixed path.
