feat: implement MCP proxy for OpenClaw tool access in contractor agent
Complete the MCP tool call chain: - contractor-agent bridge exposes /mcp/execute endpoint for tool callbacks - openclaw-mcp-server.mjs proxies OpenClaw tool defs to Claude as MCP tools - sdk-adapter passes --mcp-config on first turn with all OpenClaw tools - tool-test plugin registers contractor_echo in globalThis tool handler map - agent-config-writer auto-sets tools.profile=full so OpenClaw sends tool defs - Fix --mcp-config arg ordering: prompt must come before <configs...> flag Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
