x-ai/grok models on OpenRouter do not support the reasoning.effort
parameter and reject payloads containing it with "Invalid arguments
passed to the model." Skip reasoning injection for these models, the
same way we already skip it for the dynamic "auto" routing model.
Closes#32039

"off" is a truthy string, so the existing guard `if (thinkingLevel && ...)`
was always entering the injection block and sending `reasoning: { effort: "none" }`
to every OpenRouter request — even when thinking wasn't enabled. Models that
require reasoning (e.g. deepseek/deepseek-r1) reject this with:
400 Reasoning is mandatory for this endpoint and cannot be disabled.
Fix: skip the reasoning injection entirely when thinkingLevel is "off".
The reasoning_effort flat-field cleanup still runs. Omitting the reasoning
field lets each model use its own default behavior.

Add automatic thinking mode support for Z.AI GLM-4.x models:
- GLM-4.7: Preserved thinking (clear_thinking: false)
- GLM-4.5/4.6: Interleaved thinking (clear_thinking: true)
Uses Z.AI Cloud API format: thinking: { type: "enabled", clear_thinking: boolean }
Includes patches for pi-ai, pi-agent-core, and pi-coding-agent to pass
extraParams through the stream pipeline. User can override via config
or disable via --thinking off.
