The spawn tool accepts empty strings as valid task arguments, which
causes a subagent to run with no meaningful work. The subagent's
completion message is then routed back to the originating channel
(e.g. Signal, Discord), where the main agent processes it and may
hallucinate an unrelated response that gets sent to users.
Validate that the task parameter is non-empty after trimming whitespace.

Resolve conflicts in loop.go, config.go, config_test.go,
spawn.go, and subagent.go. Integrate upstream ToolResult/AsyncTool
pattern with multi-agent routing features. Rename mockProvider
to mockRegistryProvider in registry_test.go to avoid redeclaration
with upstream's loop_test.go.
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

- Update all Tool implementations to return *ToolResult instead of (string, error)
- ShellTool: returns UserResult for command output, ErrorResult for failures
- SpawnTool: returns NewToolResult on success, ErrorResult on failure
- WebTool: returns ToolResult with ForUser=content, ForLLM=summary
- EditTool: returns SilentResult for silent edits, ErrorResult on failure
- FilesystemTool: returns SilentResult/NewToolResult for operations, ErrorResult on failure
- Temporarily disable cronTool in main.go (will be re-enabled in US-016)
