* docs: add subscription OAuth recipe (Claude + ChatGPT/Codex)
Standalone guide for running EvoScientist on Claude Pro/Max and ChatGPT
Plus/Pro subscriptions via ccproxy OAuth, previously only partially
covered inside the macOS deployment recipe.
Documents the two Codex-route pitfalls from #323 with their exact error
strings — ccproxy's default model mappings silently rewriting gpt-* to
gpt-5.3-codex, and the backend's client-identity gate ('requires a newer
version of Codex') — plus the manual ccproxy TOML fix for self-managed
instances, account-tier model availability, verification probes, and a
troubleshooting table. Adds the recipe to the docs index.
* docs: correct subscription OAuth guidance
* docs: remove stale Codex client version guidance
* docs: show the config section to add instead of a clobbering heredoc
* docs: correct reasoning_effort default behavior on the Codex route
* docs: drop private helper import from the Codex probe
* docs: warn that local ccproxy config files shadow the global one
