Changes:

- Preserve archived Codex session registry context for card snapshots and cold resume.

- Unarchive resumed sessions without dropping title, first prompt, created time, or MCP correlation id.

- Recover missing agent labels from prompt_sent.data.agent in eventStore-backed history updates.

- Preserve and repair migrated card-history JSONL mtimes so legacy Codex snapshots keep their ordering.

- Bump workspace package versions to 0.8.13.
