Technical summary

tox discovery can ignore or misparse TOX_DISCOVER arguments.

Parse TOX_DISCOVER with command-line aware splitting and inject the resulting discover arguments into unittest discovery.

This issue is about discover argument parsing, so the change should not affect normal tox command execution.

The snippet uses native project logic; discovery arguments are parsed from the actual command line before tox forwards them to the runner. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import tox; print('smoke test OK')"
