* Switches away from the ESM-incompatible & unmaintained `ts_devserver` to `http_server`. This is the canonical server maintained by dev-infra * Switches tests away from CommonJS specific logic. e.g. require.resolve * Adjusts tests to work with Protractor spec bundling (Protractor does not support ESM execution, but we want to take ESM-written specs) * Reworks playground and benchmarks to use `app_bundle` and `esbuild` instead of loading hundreds of files individually. This also makes tests more stable and more aligned with real applications. PR Close #48521
