[wrangler] Detect configless Vite apps in autoconfig

[irvinebroque]

Detects Vite projects from package.json during automatic configuration when no more specific framework is found. For configless Vite apps, Wrangler now creates a minimal vite.config with @cloudflare/vite-plugin and can validate declared Vite versions before dependencies are installed.

  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: This improves automatic detection/configuration behavior without changing user-facing docs or adding new commands/config options.
