feat(presets): add TeamoRouter provider preset for 6 apps

Add TeamoRouter (enterprise Agentic LLM gateway) as a sponsor partner
across Claude Code, Claude Desktop, Codex, OpenCode, OpenClaw and Hermes.

- Claude Code uses bare host https://api.teamorouter.com; Codex uses
  https://api.teamorouter.com/v1 (native Responses); OpenCode/OpenClaw/
  Hermes use gpt-5.5 over the OpenAI-compatible /v1 endpoint. No Gemini.
- apiKeyUrl uses the English referral link with UTM params (in-app stays
  English; README links are per-language).
- Add localized in-app promo blurb (zh/en/ja/zh-TW).
- Add README sponsor rows below PatewayAI in all four READMEs.
- Register the teamorouter provider icon and pad the README banner to the
  standard 2.40 aspect ratio.
