Migrate to vp/vite-plus toolchain and update configs

Replace ESLint/Prettier/Husky workflow with vp (vite-plus) tooling: remove .eslintrc.cjs and prettier.config.js, drop husky pre-commit and add .vite-hooks/pre-commit (vp staged). Update package.json scripts to use vp commands, bump @halo-dev/theme-package-cli, replace vite with @voidzero-dev/vite-plus-core alias and add vite-plus, and add pnpm settings/overrides and packageManager update. Add VS Code recommendations and formatter settings, expose .vscode/settings.json in .gitignore, and adjust CI to use Node 24. Update README link and small formatting fixes. Regenerate pnpm lockfile to reflect dependency changes and other config updates; templates and vite config were also modified.
