v1.0.0 — First GA release

First GA release of @nodots/backgammon-core.

The canonical game engine for Nodots Backgammon: move validation, board state machine, dice rolling, cube logic, hit/bear-off/block mechanics, GNU position ID encoding, and the Performance Rating calculator.

Install

npm install @nodots/backgammon-core

Pairs with:

• @nodots/backgammon-types — type definitions
• @nodots/gnubg-hints — native evaluator

Highlights

• Unified presentation layer: every player sees themselves as white moving clockwise, regardless of backend direction
• activePlay.moves as the single source of truth for available moves
• Dual-number point system (clockwise/counterclockwise) handled internally
• PR calculation with standard GNU BG formula (AEL × 500)
