test: standardize test setup with integration/e2e markers and junit output (#71)

- Expand addopts with standard verbose flags
- Broaden testpaths from tests/unit to tests (discovers future dirs)
- Add integration and e2e markers
- Fix CI: use correct package name (reqstool_python_decorators), add --junitxml
- Create empty tests/integration/ and tests/e2e/ directory structure
