When the app has a <base href> (e.g. /f/), the dev server already serves everything under that prefix and the initial load resolves all module scripts relative to it. But reloaded_sources.json, which drives hot reload and hot restart, lists modules as /web_entrypoint.dart.lib.js, /packages/<app>/main.dart.lib.js, etc. The browser then requests them from the origin root, bypassing the base href. Behind a reverse proxy that only forwards /f/**, those requests 404 and hot reload breaks.

DWDS also assumes the base href is there: _removeBasePath blindly drops basePath.length characters from every server path before mapping it back to a module, so the root-relative paths were already producing wrong module lookups after a reload.

This PR prefixes the src entries with basePath so they match the initial load and DWDS' expectations.

Fixes #192433

Code Review

This pull request updates the WebAssetServer to include the basePath in the root-relative URL paths (src) for DDC library bundles, ensuring browser requests use the same prefix as the initial load. The documentation and JSON examples have been updated to reflect this change. Additionally, the tests in devfs_web_test.dart have been parameterized to verify correct path generation both with and without a baseHref. There are no review comments, and I have no feedback to provide.
