Remove Debug window feature

Debug button, DebugWindow, and the stdout/stderr tee (core/debug_log.py)
weren't wanted. developer_mode toggle stays — still gates device
Simulation Mode checkboxes and verbose terminal logging.

-core/debug_log.py
-
-Tees stdout/stderr into an in-memory ring buffer + Qt signal so the Debug
-window can show everything the app has printed since startup — including
-messages from background poll threads (e.g. "[CMLLayer] poll error: ...") —
-not just whatever gets printed while the window happens to be open.
-
-install() should be called once, early, before anything prints. The real
-streams are still written to, so running from a terminal is unaffected.
