fix(codex): stream commentary deltas through the reasoning channel

Follow-up to the salvaged #58696 (devatnull) + #41343 (annguyenNous)
commits: instead of fully suppressing commentary/analysis-phase stream
deltas, fire on_reasoning_delta so the CLI/gateway display them like
thinking text. Matches Codex CLI semantics where commentary is never
the turn's final answer, while keeping the narration visible in the
reasoning display. Adds devatnull to AUTHOR_MAP.
