Description

Move the toolchain to pnpm 11 / Node 24 LTS and bring every dependency to latest stable, except six held back to keep this a dependency bump rather than a refactor: typescript, react-day-picker, lucide-react, eslint, @eslint/js and eslint-plugin-react-hooks.

• pnpm-workspace.yaml: onlyBuiltDependencies -> allowBuilds (pnpm 11)
• tsconfig: drop deprecated baseUrl, make paths tsconfig-relative (TS 6)
• vite.config: drop manualChunks, removed by rolldown in Vite 8
• utils: NodeJS.Timeout -> ReturnType (@types/node 26)
• mockServiceWorker.js regenerated by msw's postinstall

Walkthrough

The pull request updates Node.js and pnpm versions, refreshes dependencies, changes pnpm build permissions, upgrades MSW request handling, adjusts TypeScript path resolution, updates timer typing, and removes Vite manual chunk configuration.

Changes

Toolchain modernization

Layer / File(s)	Summary
Toolchain and build configuration .github/workflows/build-and-test.yml, package.json, pnpm-workspace.yaml, vite.config.ts	CI and Volta now use Node.js 24 and pnpm 11. Runtime and development dependencies are updated. pnpm uses allowBuilds, and Vite no longer defines manual chunks.

Mock service worker request flow

Layer / File(s)	Summary
Request timing and response serialization public/mockServiceWorker.js	MSW is upgraded to 2.15.0. Requests include interception timestamps. Event-stream responses skip cloning, and response metadata is serialized from the original response.

Compatibility settings

Layer / File(s)	Summary
Type and path compatibility src/lib/utils.ts, tsconfig.json	debounce uses ReturnType<typeof setTimeout>. The @/* alias resolves through ./src/* without baseUrl.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to bbc98

The update modernizes the Node/pnpm toolchain, dependencies, build permissions, TypeScript configuration, and MSW worker behavior. No concrete current-head merge-blocking risk remains.

Poem

A rabbit checks the toolchain bright
Node hops to twenty-four tonight
pnpm carries scripts with care
Mocked streams drift through cleaner air
Tiny timers type just right
The burrow builds by morning light

As part of upgrading Vite from v7 to v8, the existing manualChunks config stopped working because Vite 8 uses Rolldown and no longer accepts our object-based configuration.
