Auto-Shield Reborn

Added

• scripts/build-neoforge.ps1 - Auto-Shield Reborn previously had no canonical NeoForge build script, so its NeoForge/26 cell had no reproducible build path and a bare gradlew build silently compiled a stale gitignored gen/ tree. The new script drives cog-gen then Gradle with per-26.X -P overrides and copies to dist/, matching the other mods.

Changed

• NeoForge 26 cells rebuilt against the now-PUBLISHED NeoForge builds: 26.1 -> 26.1.2.87, 26.2 -> 26.2.0.35-beta (previously 26.2.0.25-beta, and the 26.1 NeoForge jar had no reproducible build at all). mavenLocal() removed from the cell.
• No source or behaviour change. Server-boot smoketested on NeoForge 26.1.2 and 26.2.
