Expose internal value for isServer

Fixes #258 Expose the internal value for `isServer` for reuse across the app. * **packages/core/src/index.ts** - Add `isServer` property to the `CreateEnv` return type. - Update the `createEnv` function to include `isServer` in the proxy handler. * **examples/astro/src/t3-env.ts** - Import `isServer` value from the `env` object. * **examples/nextjs/app/env.ts** - Import `isServer` value from the `env` object. * **examples/nuxt/env.ts** - Import `isServer` value from the `env` object. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/t3-oss/t3-env/issues/258?shareId=XXXX-XXXX-XXXX-XXXX).
