KeiSeiKit installs into Claude Code, but the wizard offered no Claude under
`subscription` (only OpenAI Codex) — a Claude user picking subscription got no
Claude. Add provider `claude-code` (transport=subscription, endpoint=
local:claude-cli, auth_env=_, no API key) + 3 claude-code models (sonnet
default, opus, haiku), mirroring the codex subscription convention. Listed
before codex so it's the default pick under subscription.
