v8.1.0

Improvements

1. Fixed tree-shaking for multi-entry builds

• Changed runtimeChunk from { name: 'runtime' } to 'multiple'
• Fixed runtime chunk filter to handle 'runtime~{entry}' pattern
• Result: react-router-dom exports now ~34KB avg (was 144KB), 81% unique sizes

2. Resolve re-exports to actual source files

• Track moduleRequest for re-exports like export { add } from './add.js'
• Resolve to source file path instead of declaring file
• Result: lodash-es shows 317 unique paths (was 1)

Test Coverage

• Added test fixture for source path resolution verification
