Minecraft 26.3 Fabric Beta - custom ladder trapdoor fix

Fixes climbing from custom wood ladders through an aligned open trapdoor. Adds 13 missing wood ladders to the bundled ladder compatibility tag. Closed and misaligned trapdoors remain unclimbable.

Verified on this exact JAR: 144 native ladder/direct/aligned/misaligned/closed cases, 282 mixed-slab placement/save/drop cases, all three custom dimensions, and clean dedicated-server shutdown.

Every production class, texture, model, and bundled dependency is byte-identical to the previous approved file. Only the mod version and ladder tag changed. Previous client checks are retained; the client was not rerun for this resource-only fix. Full feature and nine-mod combination coverage remains unverified, so this is Beta.

Requires Minecraft 26.3, Java 25, Fabric Loader 0.19.5 or newer, and Fabric API for 26.3. Mo Glass and MoreLadders are bundled; avoid duplicate copies.
