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)

## [2026-02-12] - US-018
- What was implemented:
- Created SubagentTool in pkg/tools/subagent.go for synchronous subagent execution
- Implements Tool interface with Name(), Description(), Parameters(), SetContext(), Execute()
- Execute() returns ToolResult with:
- ForUser: Brief summary (truncated to 500 chars if longer)
- ForLLM: Full execution details with label and result
- Silent: false (user sees the result)
- Async: false (synchronous execution)
- Error handling uses ErrorResult().WithError() to set Err field
- Registered SubagentTool in AgentLoop (pkg/agent/loop.go)
- Added context update for subagent tool in updateToolContexts()
- Created comprehensive test file pkg/tools/subagent_tool_test.go with 9 test cases
- All tests pass
- Files changed:
- `pkg/tools/subagent.go` (added SubagentTool)
- `pkg/agent/loop.go` (registered SubagentTool)
- `pkg/tools/subagent_tool_test.go` (new test file)
- **Learnings for future iterations:**
- **Patterns discovered:** SubagentTool vs SpawnTool distinction: SubagentTool executes synchronously and returns result directly, while SpawnTool spawns async tasks.
- **Gotchas encountered:** MockLLMProvider needs to use correct types (providers.LLMResponse, providers.ToolDefinition) to match interface.
- **Useful context:** SubagentTool is useful for direct subagent delegation where the result is needed immediately, whereas SpawnTool is for background tasks.
