fix(codex-bridge): audit findings: visible permanent errors, stricter model command, unbuffered stream

From ten independent read-only audits (11 Oct 2026), verified against the code:
- a permanent gateway error (no tools, 401/402/403, bare upstream 400) ends the turn with a visible
  assistant message instead of a silent retry and an empty turn;
- "modeli ... yapma", "X modeli için test yap" and general "hangi model ..." questions are no longer
  commands; a name whose version does not fit, or that several models share, is asked back;
- the stream is forwarded as it arrives (read1) and an upstream drop is no longer logged as a client
  stop nor saved as an interrupted answer;
- a lone "." joining a running turn is removed without the hook messages after it;
- the interrupted-answer note finds the user message behind hook messages and detects completion
  by event type; a per-minute rate limit is not learned as a context window.
