ClayGrounds v0.4.4 — DAI 1.9.5 Compatibility

- Updated the pack identity for the DAI 1.9.5 MAIN/ADDON lifecycle.
- pack.mcmeta now explicitly declares this datapack as the ClayGrounds MAIN experience.
- Preserves the v0.4.3 articulated entity rigs, native entity identities, combat, progression, worldgen, UI, and authored map.
- No gameplay balance or entity presentation changes were made in this compatibility pass.
- Pair with ClayGrounds v0.4.4 Resource Pack; the resource pack now carries stable DAI companion auto-enable metadata.
