- SF2/XI loader: add a Loop XFade control (ms, 0-500) next to the loop toggle. SampleVoice crossfades the loop tail into its head for a click-free seam even when the file's loop points don't match; 0 ms keeps the previous hard wrap. Threaded through VoiceSample and all noteOn call sites. - Add a reusable RepeatButton: fires on press then auto-repeats while held with an exponentially shrinking interval (stops on release/scroll-off). Applied to every +/- stepper (tempo, MIDI channel, arrangement repeats, audition/keyboard octave, and the new crossfade). - Bump version to 0.3.0 (versionCode 3) per the minor-per-change policy.
