fix(codex-bridge): leave Codex's own models alone

User decision, 11 Oct 2026: Codex's own (subscription) models are one side,
the models we add are the other. A request for one of Codex's own models now
goes to chatgpt.com as it is: no model command, lone-dot answer, info note,
work-line instruction, half-answer note or compaction handling. Codex compacts
those chats itself; the bridge making the summary on gpt-6-astra failed four
times this morning and left Codex with 'Error running remote compact task'.

Only the bridge's own traces are still cleaned (foreign ids and bridge-made
summaries left by an added model earlier in the same chat); without any, the
body is byte-identical.

Voice switching stays among the added models. Asking for one of Codex's own
models by voice is answered with how to do it: pick it in the model picker and
send a lone dot.
