Subject: [PATCH] fix: Inline source content in source maps to prevent Webpack
 warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Source maps now embed the original TypeScript source content directly,
preventing Webpack's source-map-loader from throwing warnings about
missing source files when consuming the package.

Fixes #5549
