When using Vitest, I get warnings like:

Sourcemap for "mypath/node_modules/.pnpm/entities@4.5.0/node_modules/entities/lib/esm/decode.js" points to missing source files

The published sourcemap references source files that aren't included in the package.

Suggested fix: Enable inlineSources in tsconfig.json to embed the source content directly in the .map files:

{
  "compilerOptions": {
    "sourceMap": true,
    "inlineSources": true
  }
}

This resolves the warnings without adding extra files to the package.
