GLMMultiAgentFormatter

Multi-agent formatter for Zhipu AI (Z.ai) GLM models.

This formatter extends OpenAIMultiAgentFormatter with the same GLM-specific handling as GLMFormatter:

• At least one user message is required (error 1214 otherwise)

• Does NOT support the name parameter in messages

• tool_choice only supports "auto"; forced choices are degraded, while none removes tools to preserve the no-tool-call contract

• Does NOT support the strict parameter in tool definitions

• Unsupported sampling parameters are stripped, max_completion_tokens is mapped to max_tokens, and temperature / top_p are clamped to the GLM ranges (see GLMFormatter for details)

Usage:

`OpenAIChatModel.builder()
.formatter(new GLMMultiAgentFormatter())
.modelName("glm-5.2")
.baseUrl("https://open.bigmodel.cn/api/paas/v4")
.apiKey(apiKey)
.build();
