Ticket 089: Use public SubLLM direct Z.AI GLM 5.3

Goal and scope

Make the public subactor/subllm policy the default route for every semantic LLM request. The central policy selects direct Z.AI GLM 5.3. Keep the legacy OpenRouter path only behind an explicit T2C_USE_SUBLLM=false compatibility override; never silently bypass a requested or default SubLLM route.
