feat(telemetry): U1 — OTel 默认启用，从 optional 升级为 required 依赖
...
- pyproject.toml: 添加 opentelemetry-api/sdk/exporter-otlp-proto-grpc/
instrumentation-fastapi 到 [project] dependencies（KTD-3）
- telemetry/{tracer,metrics,tracing,setup}.py: 移除 try/except ImportError
静默回退 — 缺包现在是硬安装错误，不再是监控盲区。保留 except Exception
处理运行时错误（OTLP 连接失败），保留 enabled=false 配置开关
- setup.py: 修复已存在 bug — MeterProvider 的 readers kwarg 在 OTel SDK 1.16+
改名为 metric_readers（被 ImportError fallback 掩盖）
- agentkit.yaml: 取消 telemetry 段注释，设 enabled=true + otlp_endpoint +
service_name + export_traces/metrics
- test_telemetry.py: 更新 test_missing_opentelemetry → test_enabled_initializes_otel_tracer；
新增 TestSetupTelemetry smoke test（disabled/none 是 no-op，enabled instrument FastAPI）；
清理 unused imports/vars
Verification:
- pytest tests/unit/test_telemetry.py: 21 passed
- pytest tests/unit/test_react_compression.py: 22 passed（_OTEL_AVAILABLE patch 兼容）
- runtime check: enabled=True → OTelTracer, enabled=False → NoOpTracer

feat(telemetry): U7 OpenTelemetry integration with zero-dependency no-op pattern
...
Add telemetry module with tracing (agent/tool/llm/pipeline_step spans),
metrics (5 histograms/counters), and setup with optional OTLP exporters.
Uses no-op pattern when opentelemetry not installed. GenAI Semantic
Conventions for LLM spans. Integrated into ReactEngine, LLMGateway,
ToolBase, and FastAPI app.
