Greptile Summary

This PR upgrades Vite from v6 to v8 (which uses Rolldown as its bundler), enables the React Compiler, and performs the prerequisite refactor of all Zustand stores to make them React Compiler–compatible.

• Vite v8 / Rolldown migration: replaces @rollup/plugin-inject (Buffer injection) and @vitejs/plugin-react v4 with their Rolldown-native equivalents (@rolldown/plugin-babel, @vitejs/plugin-react v6); adds jsxImportSource: '@emotion/react' so the React Compiler understands Emotion's JSX transform.
• React Compiler: enabled via babel-plugin-react-compiler + reactCompilerPreset scoped to apps/evm/src/**, with compilationMode: 'infer' and panicThreshold: 'none' for a safe first adoption; disabled in test mode to avoid vitest interference.
• Store hook refactor: all Zustand stores rename their export from store to useStore and switch call sites from store.use.xxx() (which the React Compiler cannot recognise as a hook) to useStore(state => state.xxx) (the standard, compiler-visible selector pattern); tests updated accordingly.

Confidence Score: 4/5

Safe to merge; the Vite upgrade, React Compiler setup, and store refactor are all consistent and well-contained.

The createStoreSelectors utility still runs in every store file and adds a .use property that nothing in the codebase reads anymore — a straightforward cleanup left behind by the selector migration. The Buffer polyfill is now assigned in index.tsx's module body rather than injected per-file at build time, which means any dependency that reads globalThis.Buffer at module-evaluation time (before index.tsx runs) would see undefined; in practice wallet SDK code accesses Buffer inside function calls made well after startup, so this is unlikely to bite, but it's a behavioural difference from the old inject approach worth tracking.

apps/evm/src/index.tsx (Buffer polyfill timing) and apps/evm/src/store/index.ts (unused createStoreSelectors .use accessor)

Important Files Changed

Filename	Overview
apps/evm/vite.config.mts	Vite v8 / Rolldown migration: replaces @rollup/plugin-inject with @rolldown/plugin-babel, enables React Compiler via reactCompilerPreset scoped to apps/evm/src, adds jsxImportSource for Emotion compatibility, disables React Compiler in test mode.
apps/evm/package.json	Upgrades vite from ^6.2.5 to ^8.0.16 and @vitejs/plugin-react from ^4.3.3 to ^6.0.2; adds @rolldown/plugin-babel, babel-plugin-react-compiler, and @babel/core; removes @rollup/plugin-inject.
apps/evm/src/index.tsx	Replaces the rollup-level Buffer injection with an explicit globalThis.Buffer polyfill in the entry module body; the assignment runs after all static imports are initialized, so module-level Buffer access in transitively imported dependencies would still be undefined.
apps/evm/src/store/index.ts	Renames internal useStore to store and exports createStoreSelectors result as useStore, making the hook-naming convention consistent; all consumers updated accordingly.
apps/evm/src/hooks/useSendTransaction/tests/index.gaslessTransactions.spec.tsx	Updates mock to use function-based useStore selector pattern instead of store.use.openModal; test logic unchanged.
apps/evm/src/libs/notifications/utilities/tests/index.spec.ts	Updates vi.mock to expose useStore.getState instead of store.getState; utility functions only use .getState() (not the hook form), so the plain-object mock is appropriate.
