"""Benchmark CLI command — standardized capability benchmarking.

Implements industry-standard benchmark methodology (SWE-bench / AgentBench / ToolBench):
- Standardized TaskSet with dimension/category/difficulty metadata
- Full metrics: Accuracy / Precision / Recall / F1 / Latency p50,p95,p99 / Consistency
- Multiple runs with mean ± std and 95% Wilson confidence interval
- Failure root-cause classification (wrong_mode / wrong_tool / timeout / exception / ...)
- Markdown + JSON + HTML report generation
- Baseline comparison (↑/↓)

Three execution modes via --mode:
- mock: 全部使用 Mock（默认，快速、无 LLM 依赖）
- llm: 使用真实 LLM（需要 agentkit.yaml 配置）
- gui: 启动真实 GUI 服务器测试端到端
- all: 运行所有模式（Mock + LLM + GUI）

Tests core AgentKit components:
- preprocessing: RequestPreprocessor routing accuracy [Mock]
- overfitting: routing consistency across paraphrases [Mock]
- efficiency: component execution timing [Mock]
- tool_search: ToolSearchIndex BM25 relevance [Mock]
- event_model: SubmissionQueue / EventQueue lifecycle [Mock]
- spec_management: SpecManager CRUD operations [Mock]
- verification: VerificationLoop execute/retry behavior [Mock]
- board_meeting: BoardRouter @board prefix routing & validation [Mock]
- llm_reasoning: Real LLM intent/tool/multi-step/code/error [LLM]
- gui_integration: agentkit gui end-to-end (API/WS/frontend) [GUI]

Usage:
    agentkit benchmark                          # run all mock dimensions
    agentkit benchmark --mode mock              # explicit mock mode (default)
    agentkit benchmark --mode llm --report      # LLM mode with report
    agentkit benchmark --mode gui --report      # GUI mode with report
    agentkit benchmark --mode all --report      # all modes
    agentkit benchmark -d preprocessing         # single dimension
    agentkit benchmark --fast                   # core cases only
    agentkit benchmark --verbose                # detailed output
    agentkit benchmark --format html            # HTML format
    agentkit benchmark -o ./results             # output directory
    agentkit benchmark --runs 3                 # multiple runs (default 3)
    agentkit benchmark --baseline               # compare with baseline
