Improve codex-local adapter: skill injection, stdin piping, and error parsing

Codex adapter now auto-injects Paperclip skills into ~/.codex/skills,
pipes prompts via stdin instead of passing as CLI args, filters out noisy
rollout stderr warnings, and extracts error/turn.failed messages from
JSONL output. Also broadens stale session detection for rollout path
errors. Claude-local adapter gets the same template vars (agentId,
companyId, runId) that codex-local already had.
