Fix CI: Add maturin to dev dependencies (#27)

* docs: add comprehensive Google-style docstrings to all public APIs (#24)

Added comprehensive API documentation following Google-style docstring format:

- python/dioxide/__init__.py: Enhanced module docstring with quick start example
- python/dioxide/scope.py: Detailed Scope enum docs with usage examples
- python/dioxide/decorators.py: Complete @component decorator documentation
- python/dioxide/container.py: Comprehensive Container class documentation

All public methods now include:
- Clear description of purpose and behavior
- Args with types and detailed explanations
- Returns with type information
- Raises documenting exceptions
- Working, tested examples
- Usage notes and best practices

Documentation features:
- All examples are executable and tested
- Type hints match docstring descriptions
- IDE autocomplete shows full documentation
- help() function displays useful information
- Examples demonstrate common use cases

This completes issue #24 - Complete API Documentation

* fix(ci): add maturin to dev dependencies

Maturin was missing from dev dependencies, causing CI to fail when
running 'uv run maturin develop'. Maturin is specified in build-system
requirements but needs to be in dev dependencies for uv to find it.

* style: apply ruff formatting to decorators.py

+"""dioxide: Fast, Rust-backed declarative dependency injection for Python.
+
+dioxide is a modern dependency injection framework that combines:
+- Declarative Python API with @component decorators
+- High-performance Rust-backed container implementation
+- Type-safe dependency resolution with IDE autocomplete support
+- Support for SINGLETON and FACTORY component lifecycles
+
+Quick Start:
+    >>> from dioxide import Container, component
+    >>>
+    >>> @component
+    ... class Database:
+    ...     pass
+    >>>
+    >>> @component
+    ... class UserService:
+    ...     def __init__(self, db: Database):
+    ...         self.db = db
+    >>>
+    >>> container = Container()
+    >>> container.scan()
+    >>> service = container.resolve(UserService)
+    >>> assert isinstance(service.db, Database)
+
+For more information, see the README and documentation.
