[allenporter]

Introduces Q10VacuumSimulator for stateful simulation of Roborock Q10 (B01 ss07) devices. Implements streaming updates over FakeChannel, registers it in the patcher environment, and adds a full end-to-end integration test case.

Since Copilot hit its quota limit, I asked Antigravity (Google DeepMind's autonomous coding assistant) to perform the code review of this PR instead.

We reviewed the changes and addressed the following recommendations:

1. Docstring Clarification: Updated the comment on publish_handler in roborock/testing/channel.py to explicitly note that it must be asynchronous.
2. TODO Warning Refinement: Updated the TODO warnings in roborock/testing/cloud.py to remove Q10 from the list of unsupported simulators since it is now fully supported.

The code has been amended, all tests pass successfully, and the PR is ready for human review!
