Zero SDR v0.1.0-rc.7

[!WARNING]

Superseded by RC8. RC7 contains an application-owned udev path rejected by the current CardputerZero Store policy; do not submit RC7 to the Store.

Hardware-validation candidate; this is not yet an App Store release.

Highlights:

• Honors the official Launcher display handoff: LV_LINUX_FBDEV_DEVICE, then inherited APPLAUNCH_LINUX_FBDEV_DEVICE, then the compiled /dev/fb0 fallback.
• Makes the packaged non-root P0 preflight resolve the same framebuffer path and verify its matching sysfs node is native 320×170.
• Adds host regression coverage for framebuffer precedence plus redirected-P0 checks for both APPLaunch and LVGL overrides.
• Pins the current official Cardputer Zero v0.0.4 BSP to its published SHA-256 and verifies both fresh downloads and cached archives.
• Records audited Template, Launcher, AppBuilder, dtoverlays, and BSP revisions in the upstream compatibility guide.
• Keeps the complete Chinese README and its prominent repository-home link in the package.

• ARM64 package build and inspection: https://github.com/k1412/cardputerzero-sdr/actions/runs/31727928623

Physical Cardputer Zero USB, audio, controls, display, thermals, and 30-minute stability remain the P0 release gate tracked in issue #1.
