VAPOR COMPILER GETS LEANER, DEVTOOLS FIXES MODULE MISMATCH

Vue's Vapor compiler just shed slot wrapping overhead while DevTools v8.1.3 corrects a package.json export that was pointing to the wrong file.

The Vapor compiler landed three consecutive optimizations overnight [1][2][3]. The headline move is stripping out withVaporCtx slot wrapping entirely, which simplifies the generated code path for components using slots. That's paired with a refactor of the slot fallback model [2] and a targeted perf win that reduces v-if branch scope overhead [3]. All three changes are syncing back from the core Vue repository, which means the Vapor team is running these experiments at scale before they hit your build pipeline.

DevTools v8.1.3 shipped a fix [4] for a publishing mistake that's been quietly breaking integrations. The vite-plugin-vue-devtools was advertising `module: dist/vite.mjs` in package.json, but the actual build output was `dist/vite.js` [5][6]. ESM bundlers checking the module field would get a 404. This is now corrected to point at the real file.
