Restrict define to process.env.* keys.

When app code reads bare import.meta.env, Vite 8.0.0 adds configured import.meta.env.* definitions to the client-side object. This can expose unrelated .env values, including secrets, to clients that can access the dev server. (github.com)

Filter envDefines to process.env.*, as targets/web/build-dom-web.mjs does. Keep per-member import.meta.env substitution in createDotEnvPlugin.

Suggested fix 
-  define: envDefines,
+  define: Object.fromEntries(
+    Object.entries(envDefines).filter(([key]) => key.startsWith('process.env.')),
+  ),

Review comment at @targets/web/dev-web.mjs at line 229:
Restrict the `define` configuration in the web dev setup to `process.env.*` keys
by filtering `envDefines` before passing it to `define`. Keep per-member
`import.meta.env` substitution in `createDotEnvPlugin`.
