fix: resolve @vuerend/core in Cloudflare Worker environment

vuerend's resolveId hook redirects @vuerend/core to
virtual:vuerend/client-runtime for any environment not named 'server'.
The Cloudflare Worker environment is named 'vuefes_japan_speakers', so
it incorrectly received the client runtime which lacks defineApp and
defineRoute, causing the build to fail with MISSING_EXPORT errors.

Add a pre-plugin that intercepts @vuerend/core for non-server/non-client
environments and resolves it to the runtime-only entry directly, bypassing
vuerend's virtual module.

Also remove the wrangler.jsonc `alias` field which is ignored when using
the Cloudflare Vite plugin (replaced by Vite's resolve.alias).
