GLM models cannot run Anthropic's server-side WebSearch/WebFetch, so when a
GLM model has web search enabled and ZaiApiKey is set, GenerateMcpConfig
registers z.ai's web_search_prime HTTP MCP server and CreateCliStartInfo
allows mcp__web-search-prime__* while disallowing the native WebSearch/WebFetch
tools — otherwise the model tries the (headless-ungranted) native tool first
and only falls back to the MCP search on the second attempt.
Effort is now passed through for GLM-5.2 and newer (version compare, not a
prefix match, so 5.3/6 are picked up automatically and glm-5.2[1m]/glm-5-turbo
parse correctly); older GLM models still drop CLAUDE_CODE_EFFORT_LEVEL.
