chore(presets): remove LemonData provider and demote SudoCode to regular provider

- LemonData: delete the provider preset from all apps (claude, claude-desktop,
  codex, gemini, hermes, opencode, openclaw), remove partner promotion copy
  (zh/en/ja/zh-TW), icon index/metadata entries, sponsor ads in all READMEs,
  and the logo/icon PNG assets.
- SudoCode: drop the isPartner flag and partnerPromotionKey across all app
  presets and remove the now-orphaned partner promotion copy; it stays as a
  regular third_party provider, keeping its icon.
