2026-03-08 model fallback hard rule

User reported: a previous PR to enable GPT-5.4 support was broken again; today gateway logs show FailoverError: Unknown model: openai-codex/gpt-5.4. Tao assumed main + workers were still running 5.4.

New hard rule requested by Tao:

• If main or any execution agent falls back from openai-codex/gpt-5.4 (or 5.4 becomes unknown/unavailable), main must notify Tao immediately.
• Execution agents must be fixed to 5.4 and must not silently fall back. If 5.4 is unavailable, pause and ask Tao for model decision.
• If an execution agent is not responding, main must treat fallback/unavailability as a primary suspected cause and tell Tao (not just assume “stuck”).
