- Fixed imports to use full module paths (`indusagi.agent`)

### `src/indusagi/tools/__init__.py`
- Added exports for BaseTool, ToolContext, get_tool_context
- Added exports for development tools (Bash, Read, Edit, Write, Glob, Grep)
- Added exports for handoff functions
- Maintained compatibility placeholders for registry/ToolRegistry

## Example Usage

### Creating a Development Agency

```python
from indusagi import Agent, AgentConfig, Agency
from indusagi.tools import Bash, Read, Edit, Write, Glob, Grep

# Create agents
planner = Agent("Planner", "Task planning and coordination")
coder = Agent("Coder", "Code implementation")

# Create agency with communication flows
agency = Agency(
    entry_agent=coder,
    agents=[planner, coder],
    communication_flows=[
        (coder, planner),
        (planner, coder),
    ],
    name="DevAgency"
)

# Run terminal demo
agency.terminal_demo()
```

### Using Development Tools

```python
from indusagi.tools import Read, Edit, Glob, Grep

# Find Python files
glob = Glob(pattern="**/*.py", path="./src")
files = glob.execute()

# Search for patterns
grep = Grep(pattern="def.*:", path="./src", output_mode="content")
matches = grep.execute()

# Read and edit files
read = Read(file_path="config.py")
content = read.execute()

edit = Edit(
    file_path="config.py",
    old_string="DEBUG = False",
    new_string="DEBUG = True"
)
result = edit.execute()
```

### Creating New Agents via CLI

```bash
indusagi create-agent qa_tester --description "Quality assurance agent" --output ./agents
```

## Architecture Highlights

### Design Patterns Used

1. **Factory Pattern**: Agent creation with factory functions
2. **Template Method**: BaseTool with abstract execute()
3. **Strategy Pattern**: Different tool implementations with common interface
4. **Observer Pattern**: Hook system for lifecycle events
5. **Composite Pattern**: CompositeHook combining multiple hooks
6. **Singleton Pattern**: Global ToolContext via get_tool_context()

### Safety Features

1. **Read-before-Edit/Write**: Files must be read before modification
2. **File Tracking**: ToolContext tracks all file operations
3. **Communication Flow Validation**: Only allowed handoffs can occur
4. **Pydantic Validation**: Type-safe parameters for all tools
5. **Timeout Protection**: Bash commands have configurable timeouts

### Cross-Platform Compatibility

- ASCII characters instead of Unicode for Windows console
- Path normalization using `os.path.abspath()`
- Proper encoding fallback in Read tool (utf-8 -> latin-1)
- Platform detection in template placeholders

## Performance Optimizations

1. **Parallel Sub-Agent Execution**: All 4 phases implemented simultaneously
2. **Lazy Imports**: Templates imported only when needed
3. **Streaming Output**: Bash tool supports background execution
4. **Efficient Pattern Matching**: Glob uses pathlib with gitignore support
5. **Regex Compilation**: Grep patterns compiled once per execution

   - Persistent conversation history
   - Agent state checkpointing
   - Tool usage analytics

3. **Developer Experience**:
   - Web-based agency visualizer
   - Agent performance profiling
   - Interactive debugging tools
