v0.1.6 — Faithful timing and multiplayer speed fixes

Faithful mode now keeps simulation and visual updates at the original 35 Hz, without motion interpolation or prediction smoothing. Game-speed controls are disabled in multiplayer and remain available for single-player Source Port play.

This release brings the desktop downloads up to the fixes already deployed in the browser game. It retains the multiplayer lobbies, co-op/deathmatch, automatic QUIC with WSS fallback, and downloadable Freedoom games from v0.1.5.

Desktop packages use the standard Ebitengine renderer. The optional Raylib executable remains a separate source build.

Built from main commit f86a04c5c4139af5439c7d6b43e1c31b302d44a6. Validation: the full Go test suite, WASM compilation, all 15 browser launcher tests, and the optional Raylib build passed locally.

All four desktop release builds succeeded. The five downloadable ZIP archives were checked for integrity and matching source revision; SHA256SUMS covers each archive.

Known validation issues: the main-branch CI run fails one optional Doom II campaign test because its missing-WAD skip does not recognize a wrapped file error. The test passes locally with the WAD available. The separate vulnerability scan reports existing Go 1.26.6 standard-library vulnerabilities, also reported before this merge; dependency/toolchain remediation is not included in this release.
