v0.5.0-beta — first public beta

First public beta. Everything shipped here is live-validated against a real Ableton Live 12.4.3 on Windows:

• Full LOM reach via five generic primitives — get / set / call / resolve / children (no hand-written method per feature)
• Observers with guaranteed teardown (unobserve, client disconnect, shutdown) — Live's main thread never blocks on a socket
• Clip notes — read / add / remove MIDI notes
• Browser loading — load Live's instruments and effects onto tracks
• Save & export — save the set, render the arrangement to WAV with the rendered duration verified
• Loudness analysis — integrated LUFS (ITU-R BS.1770-4), sample peak, band energies
• Housekeeping — clean up unused tracks, switch main views
• MCP stdio server — zero-dependency, for Claude Code / Claude Desktop and any MCP client
• 43 offline unit tests, no test dependencies

Install: python install.py, then enable AI Bridge as a Control Surface in Live's preferences. See the README for the musician-friendly tour.

Known limits: third-party plugin internals are unreachable (the honest half-open story in the README); the first save of a brand-new set is manual by design.
