fix(@typegpu/cli): Production builds

[cieplypolar]

Fixes:

• waku: 0.0.0.0 isn't considered secure, so webgpu is disabled. Changed the production host to localhost
• nextjs: output: 'export' is incompatible with next start

• Waku template _package.json — waku start now binds the production server to --host localhost instead of the previous 0.0.0.0 default. This keeps the app on a loopback address, which browsers treat as a secure (potentially-trustworthy) origin, so WebGPU remains enabled in production.
• Next.js template next.config.ts — removes output: 'export', which was incompatible with the template's start: "next start" production script (static-export mode has no server runtime). distDir: './dist' is retained.

I verified the waku start --host flag against the waku source (packages/waku/src/cli.ts defines -h, --host and forwards it to runStart), so the new script is well-formed. Both changes are minimal, correctly scoped (no other template carries these patterns), and directly address the reported production-build breakage. One note, not an action: binding to localhost means the production server is only reachable on the host — LAN/device access would need a reverse proxy — but that is consistent with WebGPU requiring a loopback origin anyway.

I assume that running the production server usually means you're not running it on your own machine. What motivated this change?

[cieplypolar]

Without --host localhost, Waku prints 0.0.0.0:8080 address to the console which is not considered secure. As a result, WebGPU is disabled.
