0.7.3

Override API

• Make multi-property override application transactional, keep reference fields live, and compose callback layers through single-use ctx:base() calls to the next lower layer.
• Add block step sound, slipperiness, unbreakable, fire, declarative drops, and display-tick cadence overrides, plus item full-3D, efficiency, and entity-damage overrides.
• Allow recognized native shaped, shapeless, and smelting recipes to replace their inputs without losing stable registration identity or lookup ordering.
• Add queryable, reversible overlays for sound events, BetaMoon entity types, ore rules, biomes, fuel registrations, fuel-set includes, and container GUI presentations.
• Add callback/cadence overlays for tile entities, containers, capability operations, world services, and logical networks while keeping persistent schemas and identity fields structural.
• Validate candidates before publication, rebuild affected indexes/snapshots only, and restore exact lower/base state when a layer is removed or its owning script unloads.
