feat: support TypeScript 7

[rorychatt]

Describe the feature request

With the release of TypeScript 7, projects utilizing vite-plus and scaffolded by vp create want to upgrade their TypeScript version to 7. Currently, vite-plus specifies "typescript": "^5.0.0 || ^6.0.0" in its core packages peer dependencies, causing dependency resolution errors/warnings during installation.

Proposed Solution

1. Update the typescript peer dependency in @voidzero-dev/vite-plus-core (built dynamically under packages/core/build.ts) to "^5.0.0 || ^6.0.0 || ^7.0.0".
2. Update CLI scaffolding monorepo templates under packages/cli/templates/monorepo/ (pnpm-workspace.yaml and _yarnrc.yml) to support ^5 || ^6 || ^7.
3. Keep the development devDependencies of the vite-plus workspace itself pinned to TypeScript 6 for now, as programmatic compiler APIs in upstream libraries (like rolldown and tsdown) are not yet compatible with the TypeScript 7 API structure.

Expanding the peer range independently of the workspace compiler is sensible, but the compatibility test should exercise every code path that loads typescript from the consumer project. A small matrix using TS 5, 6, and 7 for both npm-style and pnpm/Yarn monorepo resolution would catch accidental imports of the pinned development copy.
