概要
/dev/sgcを扱うユーザー空間ライブラリ libsgc を、liblzmaと同様の WAL(image IDsgcABI 1.0、/lib/sgc.1.wal)として追加します。fndWAL を import する WAL です。FND_E_WOULD_BLOCK。cpt_sgc_flush_waitは上限付きで待つ。/dev/fb0の初期化(320×240 INDEX8 の確認、CLUT 書き込み)をcpt_sgc_display_initに集約。chip8の SGC 描画を libsgc に置き換え。boot/build.pyがsgc.1.walをビルドしてchip8に import させる。foundation/README.md、MEMORY.mdを更新。テスト
python -m unittest discover -s foundation/tests/libsgc(ホストのモデル検証と Foundation 上の WAL 呼び出し・画素確認)3/3、FND_MM=slotでも 3/3foundation/tests/chip815 件(1 skip)VM/slot とも通過、foundation/tests/sgc3/3 通過Closes #143
