What Happened? | چه اتفاقی افتاده؟

When BPB references or deploys child Workers (e.g., ⁠ydpa2w1ii9yq9k9-ig3i⁠), each child Worker has a default Cloudflare ⁠Worker URL⁠ ending in ⁠*.workers.dev⁠. Even after binding a Custom Domain to the child Worker in the Cloudflare Dashboard under Custom Domains and Routes, the panel's subscription generator still uses the primary ⁠Worker URL⁠ (⁠*.workers.dev⁠) to construct non-⁠D⁠ node endpoints.

Minimal Reproducible Example | چه فرایندی برای مشاهده این مشکل طی کرده‌اید؟

1. Bind a Custom Domain to the child Worker in Cloudflare Dashboard under Custom Domains and Routes.
2. Configure Custom Domain in the BPB Panel settings page.
3. Fetch the subscription link and import it into a client (e.g., Shadowrocket).
4. Inspect node configurations: non-D nodes still retain the hardcoded *.workers.dev endpoint instead of using the custom domain.

Generated subscription output for non-D node:
Address: <child-worker-id>.<subdomain>.workers.dev

Expected output:
Address: <child-worker-id>.<my-custom-domain>
