Initial implementation: full Ableton Live 11 OSC remote script

Covers all major Live API objects with get/set/listen/method handlers:
song, track, return_track, clip, clip_slot, device (incl. rack chains
and drum pads), scene, view, application, browser, groove.

Zero external runtime dependencies — OSC encoded/decoded in osc_server.py.
Wildcard * support for track/scene indices. Listener callbacks fire to
matching /get/ addresses for bidirectional state sync.
