chore: Markdownのインデント幅を4に固定し、リストの継続行をスペース4つに揃える

継続行がスペース2つだと、VS Codeがインデント幅を2と自動判定する。
.vscode/settings.json でMarkdownの自動判定を切って幅4に固定し、
既存の継続行もリストの記号から4つ下げた位置に揃える。
変更したファイルに markdownlint --fix をかけた分(journalのURL囲みと空行)も含む。

 - MAPの正本をキーコードにする理由の修正: Claudeは当初「VIAでは実機にキーコードしか残らず、意図を復元できないので、キーコードでなければならない」とした。
-  Codexが、意図をプロジェクト側に残す設計も可能で、難しくなるのは実機で変更された値の取り込みだけだと反論し、これが正しい。
-  採用する理由は「実機との往復を単純に保てるから」とする。

 - 「コピー」のような操作の辞書は、アプリやユーザー設定まで相手が広がるので対象外。
 - 未採用のアイデア: キートップの刻印生成にHSTを使う(PHYのラベルへ流す)。検討していないので仕様には書かない。

 ## 結論
 
 - 対象: QMK `0.34.4`(tag, commit `08c662f286ddfd12a985f57b584b02eca5af0ae6`, 2026-09-05)。masterの最新リリース。
-  ユーザーが最初の対応環境として0.34.4を採用(2026-09-24)。
-  - キーコード体系 `QMK_KEYCODES_VERSION` = `0.0.9`(quantum/keycodes.h)
-  - `VIA_PROTOCOL_VERSION` = `0x000D`(quantum/via.h。9/23時点の調査と同じ)
