Farlands Tweaks Core 1.3 - End's Delight Compat1

- Replaces Fossils and Archeology 9.3.4.0's obsolete direct references to
  ends_delight.registry.ItemRegistry and BlockRegistry.
- Resolves the same food entries through Forge registry IDs, compatible with
  End's Delight 2.6.1's ModItems/ModBlocks registry layout.
- Preserves Fossils' original plant, meat, egg, pie and explicit food values.
- Applies only while the legacy class references are present, leaving a future
  upstream-fixed Fossils implementation untouched.
