Release 1.0.0: remove support for Python 3.6, 3.7; fix linting errors (#5)

* Bump version to 1.0.0; drop support for Python 3.6, 3.7 because of requests requirement

* Test with more recent Python 3.x versions

* Fix pylint errors: missing __init__.py, import ordering, exception handling

Add customerio/__init__.py so pylint can resolve the package hierarchy.
Fix raise-missing-from, return-in-finally, and import ordering warnings.
Fix RuntimeError formatting bug where %-placeholders were not interpolated.

* mise venv for local development

* Prefer using pip from venv to uv

* Split linting out from tests

* Add lint-ci which fails only on linting errors

* Latest doc URLs
