Introduce AdapterSessionCodec interface for structured session serialization, deserialization, and display ID extraction. Implement codecs for claude_local and codex_local adapters with cwd validation — sessions saved for a different working directory are not resumed. Both adapters now return sessionParams and sessionDisplayId alongside legacy sessionId. Add isCodexUnknownSessionError detection and automatic retry with fresh session for codex_local (matching existing claude_local behavior). Inject approval context env vars (PAPERCLIP_APPROVAL_ID, PAPERCLIP_APPROVAL_STATUS, PAPERCLIP_LINKED_ISSUE_IDS) into adapter environments. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
