fix(v2/templates): bump vite-plugin-svelte for Vite 8 peer range

[haoku123]

Closes #5989

Problem

Fresh v2 svelte and svelte-ts projects fail npm install with ERESOLVE:

npm error peer vite@"^6.3.0 || ^7.0.0" from @sveltejs/vite-plugin-svelte@6.2.4
npm error   dev @sveltejs/vite-plugin-svelte@"^6.0.0" from the root project

The templates declare vite: ^8.0.13, which now resolves to 8.2.1, while @sveltejs/vite-plugin-svelte: ^6.0.0 resolves to 6.2.4. That plugin's published peer range is vite ^6.3.0 || ^7.0.0, so npm rejects the tree.

Fix

Bump the plugin to ^7.3.0 in both templates. Its peer range is vite ^8.0.0-beta.7 || ^8.0.0, and it requires svelte ^5.46.4, already satisfied by the templates' existing svelte: ^5.55.7. No other dependency needed changing.

Verification

Against the acceptance criteria in #5989:

• Fresh projects install without --force / --legacy-peer-deps. Both templates npm install cleanly (found 0 vulnerabilities).

• Supported peer combination. vite-plugin-svelte@7.3.0 + vite@8.2.1 + svelte@5.x resolve with no peer warnings.

• Both generated projects build. npm run build succeeds for both on a clean npm cache:

  dist/assets/index-BT2uU9Kw.js   24.59 kB │ gzip: 10.01 kB
  ✓ built in 1.18s
  

• Change limited to the required compatibility fix. Two lines, one per template.

Testing note: I generated each template's index.html from index.tmpl.html to reproduce a post-generation project, since the raw template dir has no index.html.

Pre-existing, not addressed here

npm run check in svelte-ts reports one svelte-check error:

Error: Type 'HTMLElement | null' is not assignable to type 'Document | Element | ShadowRoot'.
  const app = new App({ target: document.getElementById('app') })

This reproduces on master with the old ^6.0.0 plugin (installed via --legacy-peer-deps), so it predates this change and is out of scope per the last acceptance criterion. Happy to fix it in a separate PR if useful.

Poem

A rabbit hops through templates bright,
And bumps the plugin version right.
Svelte and TypeScript share the tune,
From six to seven beneath the moon.
“Builds are fresh!” the rabbit sings.
