Pull request overview

This PR refactors the Neighborhoods package structure by reorganizing classes from internal implementation packages (impl.neighborhood.maybeapi) to the public preview API (preview.api.neighborhood and preview.api.move.builtin). The refactoring also includes simplifying move adapters by removing legacy-to-new move conversion in favor of new-to-legacy conversion, and updating method names from extractPlanningEntities/Values() to getPlanningEntities/Values().

Key Changes

• Moved classes from impl.neighborhood.maybeapi to preview.api.neighborhood and preview.api.move.builtin
• Renamed methods: extractPlanningEntities() → getPlanningEntities(), extractPlanningValues() → getPlanningValues()
• Simplified move adapter logic by removing LegacyMoveAdapter and LegacyIteratorAdapter
