R Project Multicam AI v2.3.10.127 — macOS PUBLIC

This build ports the Windows v2.3.10.127 core to macOS.

Included parity:
- Same v2.3.10.127 panel + Premiere host core
- Same Auto Music Map V14 / V82-FAST editing engine
- Same beat, drop, pacing, camera, resume/checkpoint and UI logic
- Hybrid/Online Music AI with macOS Keychain support for remembered API keys
- Resource guard with native macOS memory sampling
- Verified updater core; future macOS updates can download, SHA256-check, wait for Premiere to close, and run the macOS installer
- FFmpeg auto-detection/install flow retained from the previous macOS public build
