Enhance test coverage and configuration for OpenEnv CLI

- Added coverage configuration to `pyproject.toml` to exclude specific files and lines from coverage reports.
- Introduced new tests in `test_init.py` to validate environment name requirements and handle file path collisions.
- Created `test_main.py` to ensure the main application handles exceptions and can be invoked as an entry point.
- Expanded `test_push.py` with additional tests for authentication handling, error scenarios, and validation of input formats.
