feat: adapter model discovery, reasoning effort, and improved codex formatting

Add dynamic OpenAI model list fetching for codex adapter with caching,
async listModels interface, reasoning effort support for both claude and
codex adapters, optional timeouts (default to unlimited), wakeCommentId
context propagation, and richer codex stdout event parsing/formatting.

 Notes:
 - Prompts are piped via stdin (Codex receives "-" prompt argument).
 - Paperclip auto-injects local skills into Codex personal skills dir ("$CODEX_HOME/skills" or "~/.codex/skills") when missing, so Codex can discover "$paperclip" and related skills.
