fix: correct ty version and remove unsupported --strict flag

- Fix ty version to 0.0.1a16 (current alpha release)
- Remove --strict flag which doesn't exist in ty
- Update ty commands to explicitly check src directory
- Remove strict=true from pyproject.toml ty config

ty is still in early alpha, so we're using the latest available
version with basic configuration.
