pi-agent f19e3f0633 Add MIDIUtil examples with working 90s dance compositions

- 01-basic-chord.py: chord progressions (C major)
- 02-90s-dance-track.py: 5-track 90s dance (arp, bass, pads, drums, piano)
- 03-arpeggiator.py: reusable arpeggio generator with dir/type options
- 04-single-note.py: minimal single-note example
- Rewrite compose_neon_dreams.py: cleaner track functions, proper velocity=0 note_off, tick helper
- Add README.md with setup and API reference

Uses MIDIUtil library (beats-based API) instead of mido
(clocks-based API)

MIDI Util Examples

Working examples created from the MIDIUtil source repo patterns. All examples use MIDIUtil with beats-based (not ticks-based) time, the cleanest API for MIDI composition.

Setup

pip3 install --break-system-packages MIDIUtil
sudo apt-get install -y fluidsynth fluid-soundfont-gm

Examples
