…ursorTouch#29] Adds VirtualDisplayManager (Windows-only) that creates a dedicated virtual monitor for the agent using the Parsec Virtual Display Driver, providing spatial isolation at the display level. All ctypes/Win32 calls are guarded so the module imports cleanly on macOS and Linux. 28 tests, all passing.
- test_control_center.py: update import from operator_use.agent.tools.builtin (deleted in main) to operator_use.tools.control_center; add side-effect import of operator_use.agent.tools to resolve circular import; update all patch paths. - test_computer_plugin.py: remove BEFORE_LLM_CALL assertions — 9f5d002 removed _state_hook registration from BEFORE_LLM_CALL by design (state captured inside computer_task loop, not on every main-agent LLM call). - test_browser_plugin.py: same BEFORE_LLM_CALL removal; register_hooks now only stores the hooks reference without registering any handler.
