LinTunes has spontaneously resumed playback for ~4s (then paused) four
times while trav was away — suspected phantom media-key events from the
Audioengine USB DAC's HID 'keyboard', but the pathway (MPRIS vs the
focused-window key filter) is unproven. Every control path now drops a
timestamped line in ~/.cache/lintunes/control-events.log: MPRIS Player
methods, the media-key eventFilter (with source input device where the
compositor exposes it), and Player.toggle_play/pause with position. New
lintunes/eventlog.py, 1MB rotation, never raises; conftest autouse
fixture keeps tests off the real log file.
