mock: 仮決定に沿ってモックを実装する(PHY Editor・IDX・ELC・MAP・Generator)

provisional/decisions.md の仮決定(T-1〜T-28)に従い、mock/ に Vue 3 + Vite + TypeScript のモックを置いた。
T-3 の1〜3(回転したクラスター内のドラッグと保存の往復、IDX・MAPとの連携、ELCと出力の対応表)まで。疑似デバイスとの往復(T-24)は未着手。

- KLE JSONの入出力は、KLE本家の serial.js の deserialize の結果を期待値とする fixture(tests/fixtures/kle-oracle.json)で照合した。本家のコードは取り込んでいない(T-7)
- 基本キーコードの表は QMK の data/constants/keycodes/keycodes_0.0.1_basic.hjson(1e340cd)から抽出した
- 実装は Codex(Luna)、レビューは Codex(Sol)。検証: Vitest 53件、Playwright 20件、vue-tsc、vite build
- TypeScript は vue-tsc が 7 系に未対応のため 6 系に固定した
- 操作性の改善(ELCの提供者の表示、一括配線とGeneratorのピン設定の引き継ぎ、キー内の文字のはみ出し)は別途行う
