Reviewed changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated no comments.

File	Description
requirements_all.txt	Updated python-roborock version to 3.20.1
requirements_test_all.txt	Updated python-roborock version to 3.20.1
homeassistant/components/roborock/manifest.json	Updated python-roborock version to 3.20.1 in the integration requirements

The changes are straightforward and correctly applied. The version number is consistent across all three files, which is the expected pattern for dependency upgrades in Home Assistant. No code changes were required in the integration itself, indicating this is a drop-in replacement that fixes bugs in the underlying library.
