feat: add Python, TypeScript, and Go agent monitoring SDKs

- trusera-agent-sdk/ (Python): TruseraClient, @monitor decorator, LangChain/CrewAI/AutoGen integrations
- trusera-sdk-js/ (TypeScript): HTTP interceptor, fetch monkey-patching, LangChain.js integration
- trusera-sdk-go/ (Go): http.RoundTripper wrapper, zero deps, 85% test coverage
- All SDKs support log/warn/block enforcement modes and event batching

+# Contributing to Trusera SDK
+
+Thank you for your interest in contributing to the Trusera Python SDK! This document provides guidelines and instructions for contributing.
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork: `git clone https://github.com/YOUR_USERNAME/trusera-agent-sdk.git`
+3. Create a branch: `git checkout -b feature/your-feature-name`
+4. Make your changes
+5. Run tests: `pytest`
+6. Commit your changes: `git commit -m "Add your feature"`
+7. Push to your fork: `git push origin feature/your-feature-name`
+8. Open a Pull Request
+
+## Development Setup
+
+```bash
+# Create a virtual environment
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install in development mode with all dependencies
+pip install -e ".[dev,langchain,crewai,autogen]"
+```
+
+## Code Standards
+
+### Style Guide
+
+We follow PEP 8 and use several tools to enforce code quality:
+
+```bash
+# Run linter
+ruff check .
+
+# Auto-fix issues
+ruff check --fix .
+
+# Type checking
+mypy trusera_sdk
+
+# Format code (if using black)
+black trusera_sdk tests
+```
+
+### Type Hints
+
+All functions should have type hints:
+
+```python
+def my_function(arg1: str, arg2: int) -> dict[str, Any]:
+    """Function with type hints."""
+    return {"result": arg1 * arg2}
+```
+
+### Docstrings
+
+Use Google-style docstrings:
+
+```python
+def my_function(arg1: str, arg2: int) -> str:
+    """
+    Brief description of the function.
+
+    Longer description if needed.
+
+    Args:
+        arg1: Description of arg1
+        arg2: Description of arg2
+
+    Returns:
+        Description of return value
+
+    Raises:
+        ValueError: When something goes wrong
+    """
+    pass
+```
+
+## Testing
+
+### Running Tests
+
+```bash
+# Run all tests
+pytest
+
+# Run specific test file
+pytest tests/test_client.py
+
+# Run with coverage
+pytest --cov=trusera_sdk --cov-report=html
+```
+
+### Writing Tests
+
+- Place tests in the `tests/` directory
+- Name test files `test_*.py`
+- Name test functions `test_*`
+- Use descriptive test names
+- Aim for high test coverage (>90%)
+
+Example test:
+
+```python
+def test_my_feature(trusera_client):
+    """Test my new feature."""
+    result = trusera_client.my_feature()
+    assert result is not None
+    assert result["status"] == "success"
+```
+
+## Pull Request Process
+
+1. **Update Tests**: Add or update tests for your changes
+2. **Update Documentation**: Update README.md or docstrings as needed
