Vitrallis Shell 0.1.0-beta3.9 — beta4 update bridge

This bridge release lets existing managed Vitrallis installations accept beta4’s five-executable bundle without reinstalling.

• Ships the original four-executable bundle: Shell, Terminal, Notepad and Files.
• Updates the downloader/installer to select the full v2 bundle and verify shared Arti 2.6.0 independently of the Shell version.
• Preserves application data, configuration, the previous generation and atomic update switching.

Use Settings → Device → Updates → Check / Install / Relaunch. Then update to beta4 through the same controls. This bridge does not include Tor itself.

Users who skip this release are also covered: beta4 supplies a compatible four-executable entry point, followed by one additional Settings update to complete the five-executable installation.

Validation: formatting, strict Clippy, complete Rust/Python suites, Linux CI on Rust 1.91.0 and 1.91.1, ARMv7 QEMU checks, uploaded asset/checksum verification, and the beta3.1 updater installing this release’s actual ARM bundle in an isolated PocketCHIP fixture. No installed device configuration or apps were replaced.

Assets: 16 files, covering Linux x86-64 and ARMv7 hard-float bundles, SHA-256 sidecars and matching ARM session helpers. Requires glibc 2.36+ and SDL2 2.26.5+.
