施肥計画機能を追加（年度×品種単位のマトリクス管理）
- Backend: apps/fertilizer を新規追加 - Fertilizer（肥料マスタ）、FertilizationPlan、FertilizationEntry モデル - 肥料マスタ・施肥計画 CRUD API - 3方式の自動計算API（反当袋数・均等配分・反当チッソ成分量） - 作付け計画から圃場候補を取得する API - WeasyPrint による PDF 出力（圃場×肥料=袋数 マトリクス表） - Frontend: app/fertilizer を新規追加 - 施肥計画一覧（年度セレクタ・PDF出力・編集・削除） - 肥料マスタ管理（インライン編集） - 施肥計画編集（品種選択→圃場自動取得→肥料追加→自動計算→マトリクス手動調整） - Navbar に「施肥計画」メニューを追加（Sprout アイコン） - Cursor ルールファイル・連携ガイドを削除（Claude Code 単独運用へ） Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
