Adds some tests for `render_ecma_module` which was modified in #9599.

> [!IMPORTANT]
> **This is a minor release.** Two changes alter default behavior compared to `1.0.3`. Please read this section before upgrading. Everything else is additive (new features, fixes, deps).

## ⚠️ Notable behavior changes

### 1. `experimental.lazyBarrel` is now enabled by default (#9632)

**What changed.** `experimental.lazyBarrel` now defaults to `true`. When a barrel module is recognized as side-effect-free, Rolldown skips compiling the re-exported modules that are never actually used.

**Impact.** For codebases with large barrel files (component libraries such as Ant Design, `@mui/icons-material`, etc.) this is a meaningful build-time speedup, and for the vast majority of projects the emitted output is unchanged. In rare cases where a barrel is *incorrectly* treated as side-effect-free, the optimization could drop a module that was being relied on for its side effects.

**How to opt out (backward compatible).**

```js
// rolldown.config.js
export default {
  experimental: { lazyBarrel: false },
}
```

> Note: this opt-out flag is planned to be removed in a future release. If you have a case where you must turn it off, please open an issue so we can fix the underlying detection instead.

### 2. `tsconfig` project-reference resolution now aligns with TypeScript

Upgrading `oxc_resolver` (`11.19.1` → `11.20.0` in #9549, then `→ 11.21.0` in #9634) changes how a *solution-style* `tsconfig.json` (one that only lists `references` and delegates the real settings to `tsconfig.app.json` / `tsconfig.node.json`, as Vite scaffolds) is resolved, bringing it **in line with how TypeScript (`tsc`) itself behaves**:

- **Reference match priority** (oxc-resolver [#1151](oxc-project/oxc-resolver#1151)): when the root has `references`, a referenced project that includes the file now **takes precedence over the root**, instead of the root matching it first (this is what TypeScript already does). So that project's `compilerOptions.paths` now apply.
- **`allowJs`** (oxc-resolver [#1198](oxc-project/oxc-resolver#1198)): whether a `.js`/`.jsx`/`.mjs`/`.cjs` file is included is now decided by **each referenced project's own** `allowJs`, not the root's (again matching TypeScript). So `tsconfig.app.json` with `allowJs: true` + `paths` now resolves aliases for `.js` files even when the root doesn't set `allowJs`.

For most projects this is a fix (the standard Vite `paths` aliases now resolve, closes #8468), but it **is** a behavior change if you relied on the previous behavior, where the root's `paths` / `allowJs` took precedence.

**If you relied on the old "root wins" behavior.** There is no exact toggle back, because the old behavior was the bug being fixed. The recommended path is to align your config with TypeScript: declare the `paths` / `allowJs` on the referenced project that actually owns the files.

If you must keep the old precedence while still using `references`: a referenced project's match wins, and **the first matching `references` entry takes priority** (the root is only a fallback when no reference claims the file). So extract the old root settings into their own config and list it **first**:

```jsonc
// tsconfig.json (solution root)
{
  "files": [],
  "references": [
    { "path": "./tsconfig.base.json" }, // old root paths/allowJs — listed first, so it wins
    { "path": "./tsconfig.app.json" },
    { "path": "./tsconfig.node.json" }
  ]
}
```

`tsconfig.base.json` should carry the `paths` you previously declared on the root, plus `allowJs: true` if it needs to claim `.js` files (the extension is checked against each config's own `allowJs`). With no `include`, it defaults to `**/*` under its directory and claims every file first.

Alternatively, bypass reference resolution entirely by pointing the top-level `tsconfig` option at a single config: `export default { tsconfig: './tsconfig.app.json' }`.
