Core: Allow vite-plus 0.2.x in the optional peer range

[lifeiscontent]

What I did

code/core's only use of vite-plus is the optional vite-plus/versions subpath in getVitePlusVersions() (toolchain version detection), and it's wrapped in a try/catch that degrades to null when the export is missing.

That ./versions export ships identically in the 0.2.x line — export const versions = { vite, vitest, ... } (verified against 0.1.24 and 0.2.1) — so the typeof versions.vite === 'string' check holds without any code change.

This widens the optional peer from ^0.1.15 to ^0.1.15 || ^0.2.0: a superset that keeps existing 0.1.x consumers working while letting projects already on vite-plus@0.2.x install without a spurious peer warning (or a forced peerDependencyRules override).

Why

vite-plus@0.2.x reworked how it provides the test runner (it now depends on vitest@4.1.9 directly instead of vendoring its own 0.1.x-versioned fork), so projects that have upgraded can't satisfy the current ^0.1.15 range even though the API Storybook relies on is unchanged.

Checklist

• No source change beyond the peer range — the consumed surface (vite-plus/versions) is the same across 0.1.x and 0.2.x.
• It's an optional peer (peerDependenciesMeta), so non-vite-plus users are unaffected.

Summary by CodeRabbit

• Chores
  • Extended dependency version compatibility to support a broader range of releases, improving compatibility with both current and newer versions while maintaining backward support.
