v0.2.4

eduke32-wasm v0.2.4

Web build (eduke32-wasm-web.zip): the browser/WASM Duke3D with
serverless WebRTC+Nostr P2P multiplayer -- runs on macOS/Windows/Linux
via any browser. Also live on GitHub Pages.

Native desktop builds (Linux x86_64, macOS arm64, Windows x86_64)
carry the SAME serverless WebRTC+Nostr multiplayer via a native
libdatachannel transport, wire-compatible with the browser
(native <-> browser interop; either side can host). The Windows zip
bundles its DLLs; on Linux/macOS run the binary from the archive
(./eduke32). Playable out of the box: the browser build bakes the
shareware episode in and every native archive ships the shareware
DUKE3D.GRP beside the binary (a bare binary with no game data
self-downloads it, checksum-pinned). For the full game, drop your
own retail DUKE3D.GRP beside the binary. No retail data included.
