v8.3.4

Summary

Added dev server features: support for import.meta.hot.acceptExports, serve /@vite/client and stub @vite/env, and import CSS HMR helpers from /@vite/client.
Fixed multiple HMR and build bugs: avoid mutating HMR defaults, correct preloads with chunkImportMap, wait for in‑flight stylesheets, skip rewriting unchanged adopted styles, improve restart handling, and normalize watcher paths.
Enhanced CSS handling and optimizer: resolve imported preprocessors via LightningCSS, scan deep imports with custom extensions, and skip cloning call sites lacking source maps for performance.
