Introduced `OtelMcpTracing` to provide native, specification-compliant distributed tracing for Model Context Protocol servers. - Implements official OpenTelemetry Semantic Conventions for both base RPC (`rpc.system=mcp`) and GenAI/MCP domains (`gen_ai.tool.name`, `mcp.resource.uri`). - Resolves high-cardinality span naming by standardizing on JSON-RPC methods (e.g., `tools/call`) while preserving specific targets in attributes. - Leverages `McpOperation` and `McpChain` for seamless context injection and session tracking (`mcp.session.id`). - Accurately captures tool execution failures by inspecting `CallToolResult.isError()` without relying on thrown exceptions, ensuring complete trace fidelity.
