1. leftovers from a previous mypy refactor
```python
core/testcontainers/core/config.py:42: error: Redundant cast to "str"  [redundant-cast]
            socket_path = cast("str", socket_path)
 ```
 
 Post fix:
 ```bash
#poetry run mypy --config-file pyproject.toml core
Success: no issues found in 36 source files
```

2. add mypy check to the CI under lint, also create a simple report if
something is wrong.

Add OpenFGA testcontainer module

Aligns testcontainers-python with the testcontainers community standard
wait strategy pattern used across Java, Go, and other implementations.
This provides a consistent developer experience and better
maintainability.

## Examples

From:

```
wait_for_logs(container, "Test Sample Image")
```

To:

```
from testcontainers.core.wait_strategies import LogMessageWaitStrategy

container.waiting_for(LogMessageWaitStrategy("Server started"))
```

## Backward Compatibility
No breaking changes - all existing code continues working
Deprecation warnings added to wait_for_logs() and
@wait_container_is_ready
Clear migration path provided in warning messages


### New:
core/testcontainers/core/wait_strategies.py - Strategy implementations
core/tests/test_wait_strategies*.py - Comprehensive test coverage
### Modified:
core/testcontainers/core/container.py - Added waiting_for() method
core/testcontainers/compose/compose.py - Added compose wait strategy
support
core/testcontainers/core/waiting_utils.py - Base classes and protocol

## Future Strategies to quickly follow
Foundation enables community-standard wait strategies:
HttpWaitStrategy, HealthcheckWaitStrategy, PortWaitStrategy,
CompositeWaitStrategy

## Testing
Unit tests with parameterized scenarios
Integration tests with real Docker containers
Protocol compliance verification
Backward compatibility validation

This config variable gets passed into `time.sleep`, which can work with ints and floats. Making this a float type allows polling intervals under a second, which can reduce startup times for containers that spin up very quickly.
