Add Cursor + Token Station setup article (en/zh/ja/ko)

[ethanwestfall]

Summary

• New tutorial article on routing Cursor through Token Station's GPT-5.6 Sol/Terra/Luna routes, live in all four languages (en/zh/ja/ko)
• Covers registering Token Station as a custom OpenAI-compatible provider, adding the three named model routes, and defining two Luna-backed subagents (explore, test-runner) for chat-based delegation
• Three embedded screen recordings (provider registration, custom model setup, subagent creation), following the video convention established in the GenOffice article
• Branded SVG-sourced cover image, rendered via the cover-image skill's pipeline
• Adds the four language URLs to sitemap.xml

Scoped honestly: this is a setup/configuration guide, not a full agentic-coding demo. Chat and Ask mode with Sol/Terra/Luna work end to end and are verified against the Token Station dashboard. Full Agent-mode file editing with BYOK custom models did not work reliably in our testing (a known, reported Cursor limitation around its tool-calling harness), and the article says so directly rather than overselling a capability that doesn't currently hold up. The same GPT-5.6 routes are confirmed working for real agentic tool-calling in Codex, so this is scoped as a Cursor-side limitation, not a Token Station one.

Test plan

• npm run build succeeds and generates /blog/route-cursor-through-token-station[-zh|-ja|-ko].html
• Cover image renders correctly on the listing page and as the og:image
• All three videos play correctly and stay within their container at ~375px width (no horizontal scroll)
• Confirm language switcher navigates correctly between all four versions
