feat(presets): promote SudoCode to paid sponsor across six clients

Replace the legacy sudocode.us provider (a name collision) with the new
paid sponsor SudoCode on sudocode.chat, updated in place across six
clients: Claude Code, Codex, Claude Desktop, OpenCode, OpenClaw, Hermes.

- Switch endpoints to api.sudocode.chat, add isPartner +
  partnerPromotionKey, and add four-locale partnerPromotion copy
- Claude Code / Desktop use direct passthrough (no model mapping)
- Codex / OpenCode / OpenClaw / Hermes use gpt-5.6-sol
- Remove the Gemini entry (outside sponsor scope)
- Replace the provider icon with the new brand PNG
