cli: don't fail create when the API key is skipped in immediate mode

[devin-ai-integration]

What

When the user skips the API key prompt (or --auth skip) with immediate mode on, create already scaffolds, installs deps, and skips the dev server — but it then exits with code 1, so the run reads as a failure even though the user made a valid choice. Skipping the key now just turns immediate off (exit 0), same as --no-immediate.

Changes

• create-app.ts: drop process.exitCode = 1 on the missing_api_key dev-start skip. The "Add your API key to .env" note and cd/run dev next steps still print; telemetry cli_dev_command_skipped{skip_reason: missing_api_key} unchanged.

Test Plan

• Verified locally: openui create --template openui-self-hosted --immediate with blank key and no OPENAI_API_KEY in env → scaffold + install, dev server not started, prints next steps, exit 0 (was 1).
• pnpm --filter @openuidev/cli lint:check

Checklist

• I considered backwards compatibility (only the exit code changes; scripts asserting on exit 1 for a skipped key would need updating)
