Subject: [PATCH] fix(tests): Fix Windows test failures related to click 8.2
 encoding issues

Windows uses CP1252 encoding by default, which cannot handle Unicode
characters output by click.echo(). This causes test failures on Windows
when using click 8.2+.

This fix sets PYTHONIOENCODING=utf-8 in:
- tests/conftest.py: Set at module level for Windows platform
- tox.ini: Set via setenv for all test environments

Fixes encoding issues that cause UnicodeEncodeError on Windows when
tests output Unicode characters through click.echo().
