chore(presets): refresh sponsor domains and referral links

- PackyCode: packyapi.com -> www.packyapi.ai across all 8 app presets;
  drop the api-slb.packyapi.com endpoint candidate
- RightCode: right.codes -> www.rightapi.ai across 7 app presets, keeping
  the /claude and /codex/v1 path split and adding the www prefix that the
  Codex-side endpoints were missing
- ClaudeAPI: site -> www.apito.ai, referral -> console.apito.ai/agent/...,
  endpoint -> gw.apito.ai (Claude Code and Claude Desktop only)
- APINebula: apinebula.com -> apinebula.ai across all 8 app presets,
  including the endpoint inside the Codex config.toml template
- SudoCode.chat: referral link only, /register -> /sign-up with new aff
  and utm parameters (7 app presets); SudoCode.us is a different company
  and is untouched

READMEs (en/zh/ja/de) carry the same URL updates. Brand names, icons,
i18n promo keys and README copy are deliberately unchanged.
