Sourcemap fix and HMR reload polish

A few notable fixes landed: sourcemap handling now respects environment settings, and bundled dev HMR reloads more reliably on entry churn.

sapphi-red h-a-n-a btea

Respect build sourcemap from the active environment (sapphi-red82e7aa0)

Vite now reads build.sourcemap from this.environment.config in plugin-legacy, CSS, asset URL, and worker URL transforms. This fixes cases where sourcemap behavior could be wrong in non-default environments.

Bundled dev HMR reloads when an entry can’t be re-run (h-a-n-aa236886)

The bundled dev HMR client now detects entries that no longer have a valid HMR boundary and triggers a full reload earlier and more deterministically. The update also removes the old orphan-tracking logic and adds new coverage for entry cycles and removed imports.

Alias resolution now handles $ replacement patterns correctly (btea67c965b)

Vite updated @rollup/plugin-alias to v6.0.1 and added regression tests for replacements containing $$ and $&, while preserving capture-group behavior. This closes a class of aliasing bugs that could mis-handle literal dollar sequences in resolved paths.

Other misc changes

  • Moved dynamic-import playground coverage out of optimize-deps and into its own fixture set, with expanded CommonJS interop cases.
  • Switched e2e test isolation to isolate: false and refactored shared playground test helpers.
  • Aligned fallback HTML charset casing.
  • Updated watch tests to use a new waitForRebuild() helper to avoid Rolldown rebuild flakiness.
  • Misc dependency/test fixture maintenance.
