feat: US-018 - Add SubagentTool with ToolResult support
Created new SubagentTool for synchronous subagent execution: - Implements Tool interface with Name(), Description(), Parameters(), SetContext(), Execute() - Returns ToolResult with ForUser (summary), ForLLM (full details), Silent=false, Async=false - Registered in AgentLoop with context support - Comprehensive test file subagent_tool_test.go with 9 passing tests Acceptance criteria met: - ForUser contains subagent output summary (truncated to 500 chars) - ForLLM contains full execution details with label and result - Typecheck passes (go build ./... succeeds) - go test ./pkg/tools -run TestSubagentTool passes (all 9 tests pass) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
