Extract core LLM tool loop logic into shared RunToolLoop function that can be
used by both main agent and subagents. Subagents now run their own tool loop
with dedicated tool registry, enabling full independence.
Key changes:
- New pkg/tools/toolloop.go with reusable tool execution logic
- Subagents use message tool to communicate directly with users
- Heartbeat processing is now stateless via ProcessHeartbeat
- Simplified system message routing without result forwarding
- Shared tool registry creation for consistency between agents
This architecture follows openclaw's design where async tools notify via
bus and subagents handle their own user communication.
feat(config): add heartbeat interval configuration with default 30 minutes
feat(state): migrate state file from workspace root to state directory
feat(channels): skip internal channels in outbound dispatcher
feat(agent): record last active channel for heartbeat context
refactor(subagent): use configurable default model instead of provider default
1. Remove duplicate ToolResult definition in heartbeat package
- Import tools.ToolResult instead of local definition
- Add nil check for handler before execution
2. Fix SpawnTool to return AsyncResult and implement AsyncTool
- Add callback field and SetCallback method
- Return AsyncResult instead of NewToolResult
3. Add context cancellation support to SubagentManager
- Check ctx.Done() before and during task execution
- Set task status to "cancelled" on cancellation
- Call callback with result on completion
4. Fix data race window in CronTool.addJob
- Use Lock instead of RLock for channel/chatID access
- Ensure consistent snapshot during job creation

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)
