Initial implementation of a USB-gadget-linked cooling controller: - fan_controller.c: PWM PID control, tach reading, TCP temp receiver, Unix socket IPC, safe-mode fallback, CSV logging via pigpio. - temp_sender.py: laptop-side lm-sensors/thermal_zone temp sender with auto-reconnect. - FanController.qml: Quickshell floating widget for monitoring and setpoint/manual duty control over the Unix socket.
