chore: v2.8.47 — a Codex ChatGPT pool account reaches its pane even while an older login's daemon runs

Codex >= 0.164 hands a plain TUI (no -c override) to the CODEX_HOME's
shared app-server daemon, which outlives every TUI and keeps the login it
started with. A ChatGPT pool account written into a member's auth.json
therefore reached no pane while their daemon still ran on the previous
login (reproduced on 0.164.0: the daemon kept sending the old key, a
--no-daemon TUI sent the new one). Such a pane now runs `codex
--no-daemon`, only when that binary's --help lists the flag (probed once
per path/size/mtime), so an older Codex still starts.
