-// GLM47Renderer renders messages for GLM-4.7 models.
-//
-// GLM-4.7 Thinking Modes (ref: https://docs.z.ai/guides/capabilities/thinking-mode):
-//
-//  1. INTERLEAVED THINKING
-//     The model thinks between tool calls and after receiving tool results.
-//     This enables complex step-by-step reasoning: interpreting each tool output
-//     before deciding what to do next. Thinking blocks are preserved and returned
-//     with tool results to maintain reasoning continuity.
-//
-//  2. PRESERVED THINKING
-//     The model retains reasoning content from previous assistant turns in context.
-//     This preserves reasoning continuity across multi-turn conversations. The
-//     upstream API has a "clear_thinking" parameter to control this:
-//     - clear_thinking=true:  clears reasoning from previous turns (outputs </think>)
-//     - clear_thinking=false: preserves <think>...</think> blocks from previous turns
-//
-//  3. TURN-LEVEL THINKING
-//     Controls whether the model should reason on each turn. The upstream API
-//     uses "enable_thinking" parameter:
-//     - enable_thinking=true:  outputs <think> to start reasoning
-//     - enable_thinking=false: outputs </think> to skip reasoning
-//
-// OLLAMA DEFAULTS:
-//   - Thinking is ENABLED by default (thinkValue=nil or true outputs <think>)
-//   - Thinking is PRESERVED by default (reasoning content from previous turns is always
-//     included in <think>...</think> blocks, equivalent to clear_thinking=false)
-//   - Users can disable thinking per-turn via thinkValue=false
