workflow: use esbuild for dev scripts

.github/contributing.md

@@ -123,16 +123,19 @@ The `dev` script bundles a target package (default: `vue`) in a specified format
 ```bash
 $ nr dev

-- The `dev` script also supports fuzzy match for the target package, but will only match the first package matched.
+- **Important:** output of the `dev` script is for development and debugging only. While it has the same runtime behavior, the generated code should never be published to npm.
+
+- The `dev` script does not support fuzzy match - you must specify the full package name, e.g. `nr dev runtime-core`.
 
 - The `dev` script supports specifying build format via the `-f` flag just like the `build` script.
 
 - The `dev` script also supports the `-s` flag for generating source maps, but it will make rebuilds slower.
 
+- The `dev` script supports the `-i` flag for inlining all deps. This is useful when debugging `esm-bundler` builds which externalizes deps by default.
+
 ### `nr dev-compiler`
 
 The `dev-compiler` script builds, watches and serves the [Template Explorer](https://github.com/vuejs/vue-next/tree/master/packages/template-explorer) at `http://localhost:5000`. This is extremely useful when working on the compiler.
