Pull request overview
This PR refactors warning messages in the code splitting logic to use the centralized logger module instead of direct console.warn calls, improving consistency with the project's logging infrastructure.
Changes:
- Replaced 8 instances of
console.warnwithlogger.warnin the code splitting options handler - Updated test spy to monitor
console.loginstead ofconsole.warnto align with the testing logger implementation - Modified the testing logger to use wrapper functions instead of direct assignment to enable proper test spying

## [1.0.0-rc.3] - 2026-02-04
⚡ Remove Unnecessary Default Export Assignment
- Eliminates redundant variable assignments when exporting default values
- Reduces output bundle size and improves code clarity
```js
// index.js
var x = 42;
export default x;
// Before
var x = 42;
var entry_default = x;
export { entry_default as default };
// After
var x = 42;
export { x as default };
```
🐛 Avoid Unnecessary Facade Chunks
- Keep user-defined entry modules in their own chunks
- Reduces HTTP round trips and improves startup performance
```js
// main.js (entry module)
import { a } from './lib.js'
console.log(a)
// lib.js
export * from './counter.js'
// counter.js (entry module)
export const a = 100
// Before
dist/
├── main.js → import { a } from './counter-chunk.js'; console.log(a)
├── counter.js → export { a } from './counter-chunk.js' // ❌ facade chunk
└── counter-chunk.js → export const a = 100
// After
dist/
├── main.js → import { a } from './counter.js'; console.log(a)
└── counter.js → export const a = 100
```
