feat(presets): add CCSub provider across six apps

Add CCSub, a multi-model aggregator partner, as a preset for Claude, Codex, OpenCode, OpenClaw, Claude Desktop, and Hermes. Each preset carries the referral signup link as apiKeyUrl.

- Register the ccsub icon via iconUrls (1.1MB SVG URL import) + metadata
- Add partnerPromotion copy in zh/en/ja
- List CCSub in the sponsor section of all README locales
- Use gpt-5.5 and gemini-3.1-pro as the OpenAI/Gemini model ids
