fix(wip): correctly capture codex session UUID from nested directory structure

Codex stores sessions as ~/.codex/sessions/YYYY/MM/DD/rollout-<ts>-<uuid>.jsonl.
The old code just listed top-level dirs, grabbing "2026" instead of the UUID.
Now finds the most recent .jsonl file and extracts the UUID with grep.
