defineConfig always injects vite-plus:vitest-resolver into vp build / vp dev even when Vitest isn't used

Describe the bug

defineConfig from vite-plus always prepends Vitest-only plugins into every Vite config, including for vp build / vp dev:

• vite-plus:vitest-resolver
• vite-plus:auto-inline-matcher
• vite-plus:coverage-version-guard

Projects that use Vite+ for toolchain (fmt / lint / build) but run tests with another runner (e.g. Bun's bun:test) still pay for these plugins on every production build.

Rolldown/Vite plugin timings report:

[PLUGIN_TIMINGS] Your build spent significant time in plugins. Here is a breakdown:
  - vite-plus:vitest-resolver (87%)

The resolver is an enforce: "pre" resolveId hook, so it runs on every module resolve. It early-returns for non-vitest / @vitest/* ids, but with a large graph that still dominates plugin time.

There is no documented opt-out. lazyPlugins only gates user plugins during config-metadata loads; it does not skip these injected plugins on build/dev. vite-plus/prefer-vite-plus-imports also pushes app configs to import defineConfig from vite-plus rather than vite, so switching away isn't a clean escape hatch.

Reproduction

1. Use import { defineConfig } from "vite-plus" in an app vite.config.ts
2. Do not configure or run vp test / Vitest
3. Run vp build (with plugin timings enabled)
4. Observe vite-plus:vitest-resolver near the top of [PLUGIN_TIMINGS]

Expected

Vitest helper plugins should only be injected when running tests (vp test / Vitest), or there should be an explicit opt-out for projects that don't use Vitest.

System Info

• vite-plus: 0.2.5
• Tests: Bun (bun:test), not Vitest
• Apps build via vp build

Suggested fix

• Gate injection on test command / presence of test config, or
• Add a config flag such as test: false / vitest: false to skip injection, or
• Document a supported way to opt out without fighting prefer-vite-plus-imports

Tái hiện vấn đề với một vite.config.ts import defineConfig từ vite-plus và chạy vp build khi đã bật thời gian của plugin. Đọc các thay đổi đối với resolver và auto-inline matcher trong các PR 356 và 1113, sau đó theo dõi cách vp build, vp dev và vp test đưa chúng vào; hoàn thành có nghĩa là các lệnh không phải lệnh test không còn phát sinh các plugin chỉ dành cho Vitest hoặc có một tùy chọn opt-out được lập tài liệu.
