fix(codex-link): summarize with a subscription model, reject tiny summaries, describe added models

Model switch lost the conversation: on 10 Oct a 1 MB thread was compacted by the
newly selected small model into 2201 characters. The compaction summary for a bridge
model is now written by a subscription model (ozet_kopru.ozet_modeli, default
gpt-6.1-sol); if that request is refused before it starts, the target model is used
as before. A summary far shorter than the conversation warrants is not accepted:
Codex gets response.failed and keeps the history.

The line under each added model no longer repeats its name. Teams show their
members, fallback chains their order, single models their provider and the traits
readable from the name; the text fits one phone row (30 characters).

Also normalizes tool call ids in the streamed response so Codex persists ids the
subscription backend accepts (fc_ -> ctc_), and bumps the bridge protocol to 6.
