feat(tools): implement M11 subagent system with task routing
Add tools-task crate with subagent registry and tool whitelist system:
Core Features:
- Subagent struct with name, description, keywords, and allowed tools
- SubagentRegistry for managing and selecting subagents
- Tool whitelist validation per subagent
- Keyword-based task matching and agent selection
Built-in Subagents:
- code-reviewer: Read-only code analysis (Read, Grep, Glob)
- test-writer: Test file creation (Read, Write, Edit, Grep, Glob)
- doc-writer: Documentation management (Read, Write, Edit, Grep, Glob)
- refactorer: Code restructuring (Read, Write, Edit, Grep, Glob)
Test Coverage:
- Subagent tool whitelist enforcement
- Keyword matching for task descriptions
- Registry selection based on task description
- Tool validation for specific agents
- Error handling for nonexistent agents
Implements M11 from AGENTS.md for specialized agents with limited tool access.
