Adds signed in-app updates with launch-time checking and hourly checks while LightX studio is running. Updates download, install and relaunch from the app, preserving the existing unsaved-project confirmation. Includes all previous lamp-center and timeline fixes.

Expanded composite-effects editing with range selection and zoom. Improved animation timeline scrolling, one-pixel layer spacing, waveform and rhythm workflows, media capture/import, and local/cloud project opening. Sharper lamp outlines at high zoom. Redesigned the software update window and enabled the native online update channel. Improved startup runtime authorization. Includes release symbol trimming with private diagnostic archives.

LightX studio macOS ARM64 首个公证候选，包含原生同层选区删除及 Qt 对照修正，启用独立 lightx-studio-mac 更新通道。
