fix(release): publish standalone desktop binaries

[ThisIs-Developer]

What changed

• build each Neutralino platform target separately with embedded resources
• publish seven self-contained release binaries instead of a portable application ZIP
• fail the release build if any expected platform binary is missing
• document the standalone distribution layout

Why

The previous workflow copied executables from a portable bundle without embedding resources.neu. A downloaded executable therefore lacked the application resources and could fall back to the Neutralino website.

Building one target at a time keeps memory use bounded while producing independent Windows, Linux, and macOS downloads.

Validation

• npm run build
• generated exactly seven binaries with no resources.neu and no application ZIP
• verified Linux ELF, macOS Mach-O, and Windows PE signatures
• launched the Windows binary and confirmed the Markdown Viewer window
• uploaded the v3.9.2 release assets and downloaded them back; all SHA-256 hashes matched
