Upscaled

# Upscaled 0.1.0+26.2-alpha-4

A platform release: Upscaled now runs on NeoForge as well as Fabric, and a
dependency bug that could crash the Fabric version on minimal installations
is fixed.

The mod has been restructured so that all upscaling code is shared between
loaders; only a thin shim per loader differs. Pick the jar that matches your
loader — the feature set is identical on both.

## What's new

- **NeoForge support.** A separate `upscaled-neoforge` jar runs on NeoForge
  (26.2 beta line, built against NeoForge 26.2.0.12-beta). Same features,
  same options, same `config/upscaled.json`, same bundled natives — DLSS and
  FSR 3 both work identically on either loader.
  - Known NeoForge issue: NeoForge's early loading screen creates the game
    window in OpenGL mode, which the experimental Vulkan renderer cannot use
    (`GLFW error 65540` at startup). Until NeoForge addresses this, set
    `earlyWindowControl = false` in `config/fml.toml`.
- **Sodium settings integration on both loaders.** The Upscaled tab in
  Sodium's video settings screen (added in alpha 1) now registers on
  NeoForge as well, through the same official Sodium Config API. Sodium
  remains optional on both loaders: without it, the options stay in the
  vanilla **Options → Video Settings → Upscaled** section.
- **Fabric API is now a declared dependency** (Fabric version). Earlier
  alphas silently relied on Fabric API for asset loading and for access to a
  renderer internal: without it installed, options showed as raw translation
  keys and enabling upscaling crashed the game. The renderer access is now
  self-contained via the mod's own access widener, and the remaining
  requirement (`fabric-resource-loader-v0`) is declared properly, so the
  loader reports a clear error instead of crashing mid-render. NeoForge has
  no such dependency: the `upscaled-neoforge` jar is standalone.
- Internal: multiloader project layout (`common` + `fabric` + `neoforge`).
  No user-facing changes on Fabric beyond the dependency fix.
