  gateway paths preserved); drop api.claudecode.net.cn backup endpoint
  from endpointCandidates in 5 presets
- AICoding: full domain migration .sh -> .inc (bare domain + api.
  subdomain, invite code unchanged); README brand copy now plain
  "AICoding" without TLD suffix

Covers 8 preset files and all 4 README languages. Icons, promotion
keys, i18n copy, and legacy migration ids unchanged.
