Build initial Windows desktop port v0.1.0

[lestx05]

What changed

• restores the missing MiniDayZ Plus 1.2 game assets reproducibly from the exact upstream commit referenced by the imported README
• adds a checksum-verified asset sync step instead of committing thousands of generated game files
• implements a secure Electron desktop shell with a stable custom origin, persistent saves, full-screen/windowed modes, single-instance behavior, and safe external navigation
• adds byte-range asset responses for Construct 2 audio
• adds project integrity checks, protocol tests, dependency pinning, attribution, changelog, and documentation
• adds a least-privilege Windows CI build that smoke-tests startup, produces a portable x64 executable, writes SHA256SUMS.txt, and publishes versioned releases from main

Root cause

The initial repository import contained package metadata but omitted both folders required by it: desktop/ and docs/. The project therefore could not start or build. The original README identifies NextDev65/MiniDayZ as the source; this change pins its Plus 1.2 build at commit 40ac9cf58af806e2d7c1c0638f6c3214042239b7 and verifies the archive SHA-256 before use.

Validation

• pnpm run verify: 1,877 game files verified
• 8/8 Node tests passing
• pnpm audit --prod: no known vulnerabilities
• Linux Electron package assembled successfully
• native Windows smoke test opened Electron, instantiated the Construct 2 runtime, and loaded local game assets
• native Windows portable build completed and its uploaded artifact digest was verified
• executable: MiniDayZ-PC-0.1.0-x64.exe (107,015,324 bytes)
• executable SHA-256: bab2229e0027519a19e0fd07f556d013cf824ee8e60cb0ce1f4aa7f25526965d

Impact

This establishes desktop-port version v0.1.0. No minified gameplay logic was modified in this first-pass stabilization.
