Greptile Summary

This PR reverts the Vite v8 + React Compiler upgrade (#5639) to allow further testing, downgrading vite back to v6 and @vitejs/plugin-react back to v4 while removing all Babel/React Compiler related dependencies. Alongside the toolchain revert, the store export naming convention is restored to the pre-upgrade pattern (export const store with store.use.X() consumption) and all consumers are updated consistently.

• Toolchain revert: removes babel-plugin-react-compiler, @rolldown/plugin-babel, @babel/core, and @types/babel__core; downgrades @vitejs/plugin-react to ^4.3.3 and vite to ^6.2.5.
• Buffer polyfill: runtime globalThis.Buffer injection in index.tsx is dropped; @rollup/plugin-inject in vite.config.mts remains the build-time polyfill, matching the state before the upgrade.
• Store API + icon: all zustand stores revert their public export from useStore back to store, with usage sites updated to store.use.X(); the swap icon is renamed back to switch.

Confidence Score: 5/5

Safe to merge — the change restores a known-good toolchain configuration and consistently updates all affected call sites.

Every changed file is either a mechanical dependency downgrade, a store rename applied uniformly across all consumers, or a test update mirroring the production change. The pre-upgrade Vite v6 + plugin-react v4 configuration was already proven stable, the Buffer polyfill path via @rollup/plugin-inject was already in place before the upgrade, and no new logic is introduced.

No files require special attention.

Important Files Changed

Filename	Overview
apps/evm/vite.config.mts	Reverts React compiler setup: removes babel/rolldown plugins, downgrades @vitejs/plugin-react to v4 and vite to v6; Buffer polyfill is now handled exclusively by @rollup/plugin-inject (matching the pre-upgrade state)
apps/evm/package.json	Removes @babel/core, @rolldown/plugin-babel, @types/babel__core, babel-plugin-react-compiler; downgrades @vitejs/plugin-react to ^4.3.3 and vite to ^6.2.5; adds @rollup/plugin-inject
apps/evm/src/store/index.ts	Internal variable renamed from store to useStore; public export renamed from useStore to store — reverting the naming introduced by the React compiler PR
apps/evm/src/index.tsx	Removes runtime globalThis.Buffer polyfill (now handled at build time by @rollup/plugin-inject); import order adjustment; matches the pre-upgrade state
apps/evm/src/components/Icon/icons/switch.tsx	New file adding the SVG switch icon — this is actually a rename back from swap.tsx (which was renamed to swap by the React compiler PR); usage in PairInfo updated accordingly
apps/evm/src/libs/notifications/utilities/index.ts	All useStore.getState() calls updated to store.getState() to match the reverted store export name
apps/evm/src/hooks/useSendTransaction/tests/index.gaslessTransactions.spec.tsx	Mock updated from useStore selector pattern to store.use.openModal() pattern, consistent with the reverted store API
apps/evm/src/hooks/useUserChainSettings/tests/index.spec.tsx	Mock migrated from the useStore selector pattern to the store.use.* hook pattern; the UserChainSettings type import is dropped in favour of directly setting mock return values
yarn.lock	Lock file updated to reflect vite v6, @vitejs/plugin-react v4, @rollup/plugin-inject addition, and removal of Babel-related React compiler packages
