Sync applicable 26.1 changes to 1.20.1

[rsdadada]

Summary

• sync the applicable disable-state behavior from 26.1, including merged swimming/crawling handling, fall-flying support, deterministic legacy config migration, and current config labels
• align direction key ordering, English/Chinese translations, and the 0.7.9-beta mod version
• add optional Entity Model Features animation pausing during model-view capture and restore same-name Disable draft preview
• preserve the 1.20.1-specific YSM projection sampling implementation introduced after the previous backport

Compatibility and scope

• targets Minecraft 1.20.1 and Java 17 across Common, Fabric, and Forge
• retains nullable legacy config aliases so existing outTick, swimOutTick, and disableWhenCrawling values migrate and serialize away
• leaves README files, issue templates, CI, Gradle wrapper/dependencies, codecs, mixins, and unrelated sources unchanged
• keeps YSMCompat.java and TetrahedralProbeSet.java byte-for-byte unchanged from the current 1.20.1 baseline

Validation

• gradlew --no-daemon --no-parallel clean build -PcommitSHA=dce29bf59688bf3077673a9cab1f4459d7d8321c with Temurin JDK 17.0.16
• dependency-free migration assertions for legacy key priority, cleanup, clamping, and crawling-to-swimming migration
• Fabric and Forge remapped JAR presence, loader metadata, and 0.7.9-beta metadata checks
• Java 17 Common/Fabric/Forge compilation, JSON parsing, semantic contract checks, git diff --check, exact file-scope audit, and zero-diff YSM preservation audit
• reflected EMF API v9 method signatures checked against the current official 1.20.1 Fabric and Forge artifacts

Interactive checks still pending

• Fabric and Forge client startup/model-view smoke tests
• EMF animation pause/resume behavior in a live client
• unsaved same-name Disable draft preview in a live client
• YSM multi-angle binding regression with YSM installed
