Replace mark3labs/mcp-go with the official SDK for coder exp mcp server. Tool registration reuses coderd/mcp's RegisterSDKTool adapter, preserving the allowlist, conditional registration of user-authenticated tools and coder_report_task, and stdout purity (protocol frames only, logs to stderr). The SDK enforces the MCP lifecycle, so test fixtures now send a spec-compliant initialize handshake before other requests.

Stack Context
PR 2 of 6 in a stack that migrates every Coder MCP surface from the archived
github.com/mark3labs/mcp-golibrary to the officialgithub.com/modelcontextprotocol/go-sdkv1.7.0.Stack: #28056 -> #28057 -> #28058 -> #28059 -> #28060 -> #28061
Why
coder exp mcp server(stdio) now uses the official SDK server withmcp.IOTransportover the invocation's stdin/stdout, and reuses the sharedcoderd/mcp.RegisterSDKToolhelper from PR #28056 so both servers register tools identically.nopWriteCloserprevents the SDK from closing the invocation's stdout.notifications/initializedbeforetools/listbecause the official SDK enforces the protocol lifecycle.
